Anakin and his wife:
As I said many times before, making Anakin go right to Padmé's after Palpatine confessing he's the Sith Lord would be a hon-ron. By this, you add depth to the marriage relationship, and uncertainty, and perhaps even manipulative intelligence to Anakin's character. The best thing? The actions are speaking; there'd be no wooden dialogue!
To do this and yet not affect the development of the plot, we've to state how would the Jedi realize about Palpatine's identity. I've suggested that as "the dark side clouds everything" it could even be clouding the Jedi's minds so that they don't act specifically as they should. They'd rather be a little jerks here and convey in a council season (the one that there's Windu and almost the rest are holograms, which is not at the council chamber) that the Chancellor will be removed when Grievous is dead. This scene may need a little edition/tweakering to get moving though I suppose it's not a big deal.
POSSIBLE EXPANSION OF THE IDEA:
Once more, the dark side clouds everything, so considering there's a deleted scene that shows almost the same content that "the hologram council scene"; that deleted scene could make it to an edit since it shows only ObiWan, Yoda and Windu, and it'd lead us to think "hey, these are three Jedi that are making decissions as if they were even upper than the council". (This would make some of Anakins suspicions and angers be reasonable, after all he's not that wrong about the Jedi being a little jerks).
PRO of this expansion!:
Showing this "high command" of the Jedi order, even above the rest of the council
Giving more reasons to Anakin (and through him, till this point of the movie, to the spectator) to be unsure about the Jedi.
------------------------------------------
ObiWan gets sent to Utapau to fight Grievous , and in the meanwhile
Anakin turns
-Palp tells Anakin (in his office) what to do... "the sith will rule the galaxy, etc."
- Cut to somewhere else (am I the only one that feels it's too rushed how far Anakin gets to do his "first strike"???
- Cut back to Anakin first strike with your amazing new score. After this comes the part when I say we need to see another important character ... ok here's the novelty: that character is Palpatine. The idea would be: "while Anakin is killing people, what is Palpatine doing, sitting in his office??": NO.
SO:
- Cut to Palpatine telling Cody "execute order 66"
- Cut to somewhere that's not Utapau.... maybe Padmé criying when she sees fire in the Jedi's.
- Cut to Utapau. ObiWan reunites with Cody, and then Cody shots him.
THE DETAIL: Cody would be giving him his lightsabre! And he says I think you'll be needing this! Left to the viewer's interpretation whether Cody was helping ObiWan or not.... If this is done well, you would have just made another character a little more deep!.
Besides, this way it'd be better, because you'd be generating another tension. You see what happens to Anakin and in the middle of it, you see the emperor telling a clone commander to "execute order 66". So it makes you wander what's gonna happen with ObiWan. There you generate the tension, but again, you put something in the middle: Padmé's scene, and maybe more (the more the better).
And when you come back to Utapau, you see the Clone might have developed some affection (?) for his Jedi General who chose to serve...
TILL HERE, THE RADICAL BUT EASILY DOABLE STUFF.
NOW...
Obi Wan's scape and afterwards.
You might have seen that Bob Garcia replaced the hologram in kenobi's fighter by a radio wave. This allows you to not only replace the hologram, but the whole message.
The video message of Palpatine's asistant should be replaced with the radio again, and it'd be something like:
"His majesty (HERE is when you insert a quick shot of Obi and Yoda putting their best oh-shit faces) has requested you for a special season of the senate."
(The WTF faces ar mainly due to "his majesty"... Palpatine hasn't even declared the Empire yet. This is just a way to "inform" Yoda and ObiWan what's really happening, without giving it in the mouth, so once again, you make the characters more clever.
After the tantive's cockpit scene, you should cut entirely the lame CGI scene of ObiWan and Yoda establishing the emergency signal in Coruscant. Why?
Because in a character-centred plot, we'd be mainly with ObiWan. So I guess Yoda could go and establish the signal on his own, while Obi Wan would be worried about Anakin (it's a tragedy, he's worried about his friend, but he doesn't know he's a killer). And since ObiWan knows about Anakin and Padmé, he'd know exactly where to go in order to find his friend
---- Cut to Mustafar, and end of this suggestion----
POSSIBLE EXPANSION/VARIATION OF THE IDEA:
Even if the "best friends" plot line is a radical change, it came to my mind the idea of another possibility that could enhance or replace what I formerly suggested.
Well besides being worried for his best friend... perhaps ObiWan thinks that Anakin's time has come...
I mean, APART from the friendship preocupation, ObiWan wants to find Anakin because he is considered "the chosen one", "the only one who could destroy the sith".... so they need to find him the same way you need to find a baseball bat when someone's punching you (bad methaphore). They need him as a weapon. And when ObiWan goes to mustafar and sees what happen... well, everything crumbles down.
How to do this??
Right after the Tantive's cockpit scene, cut to the Tantive's corridor scene, and alter the dialogue so that it looks like this (once again with dialogue from the original footage)
ObiWan: Have we received any message from the "temple" (here change "temple" and put ANAKIN)? There's too much at stake master. He must know.
Yoda: (Silence)
ObiWan: With all of your respect master, isn't he the chosen one? We need him
Y: a prophecy that coulda been misunderstood
O: He is my best friend, I know he won't fail me (or something)
The way I've immagined this, the message that Kenobi gets from bail's ship should be replaced.First of all, it won't be Bail Organa, bail Organa's a senator, why would he be getting radio mesagges from anyone. Logically, the message should be received by the commander of his ship: Antilles. Plus, this would be a fan service to OT.
SINCE WE'VE ESTABLISHED OBI WAN AND ANAKIN ARE VERY CLOSE TO EACH OTHER the dialogue could be something like this.
Captain:"Captain Antilles here. This is Senator Organa's ship"
ObiWan: "Captain my clonetrooper fired at me...."
Captain:"...it seems that there's been a Jedi rebellion sir. The jedi are being hunted. We'll send you our cordenades"
(Comunication off)
OBI WAN (face gesture of "dammit"): ANAKIN!! (worried about him being murdered as the rest of the Jedi). ( this is the tricky line to do)
----well, obiwan reaches the tantive, Yoda does it too, and in the cockpit----
