Sorry for double posting but I have to say If it could be done but It would probably be perhaps extremely difficult.

The Prequel trilogy done in a 70's sci-fi movie style. Not only would it grant a lot of artistic licence in terms of design but it could borrow a lot from this era.

Droid Cameo's for instance from silent running and the Black hole and it was when I thought of the black hole I realised something.

Should battle droids look like this?

This is one scary droid and somehow I think it would be a perfect replacement for the battle droids. The destroyers are ok but they could be easily made to resemble this a little more and atleast they are intimidating

You can see him in action here

Not totally saying that it should be this but at least it is intimidating and perhaps a good design to start or modify or even just copy it and put it in there I'd still be a lot happier with this than the current battledroids

also thinking with a mentality of how would people go about creating something in the 70's to achieve a warrior droid rather than all the special effects we have today... Not many moving parts but it's rigidity is not only a bonus in terms of ease of implementation but it is also a lot more intimidating that it hovers about and can rise over you and has spinning metal blade hands for close combat and perhaps mounted lasers.

It serves it's purpose and has less moving parts that could get broken at joints during battle

So in my book this design or similar is a plus on many counts
