I'll have to watch it again (of course in the old days I could pop on youtube for a quick refresher) but even if there are continuity issues (nothing new in a Star Wars film, something you are probably more qualified than most to attest to) it does seem that your main objection is to the actual blocking conceit itself rather than any positioning hiccup.
For me the reason why ANH's opening is so iconic is it's pure cinematic storytelling.
From that moment you know the score.
Small Rebellion up against a giant beweaponed evil Empire.
The opening to TPM should be the blockade arriving.
Tiny little defensive planet surrounded by a fleet of greedy feds, like a swarm of giant pac-men going for the innocent blue dot.
Not a tiny little ship representing the Galactic Republic arriving at a large in frame world with lots of ships that mysteriously vanish in the last act.
I would use blocking in Jedi to show the huge bulk of a Star Destroyer dwarfed by the Executor (as in ESB) and then have that dwarfed by the metal tendrils of the unfinished Death Star.
With ROTS Coruscant has always been shown as this safe spot.
Nothing can touch the capital, it's towers always glistening even when there is slavery and villainy and bloodshed.
The general idea of fooling the audience into expecting another safe Coruscant reveal only to have it turn into a chaotic battle was the right thing to do. I would have shown the city itself largely in ruins.
Towers over turned, spires snapped off, Coruscant blitzed.
After getting such a shock I could imagine the Senate turning to Palpatine for easy answers even if it meant the formation of the Empire.
