I just thought of two models that could possibly be done(and I'd like to have them in my model/skin collection
). I don't know if they are already being worked on or not or if someone has already made them, but, here goes...
First off, how about a Super Battle Droid model? It would need to have some type of weapon mod included, because Super Battle Droids have laser cannons mounted on their wrists. It would probably replace the usual blaster pistol in the weapon mod. So, for instance, the SBD would have his arms at his sides or something when you choose the wrist lasers, and when you fire them, the SBD holds his arm out and fires, just like in the movie. Or you could just have it when you choose the weapon, he has his arm out even if you don't fire it, but oh well. The lasers would have to fire repeatedly(Like either the alt fire on the E11 or the primary fire on the Imp Repeater rifle), and the lasers should be red too. For the sounds, the weapon sounds could be taken from AOTC or just use the weapon sounds from the Imp Repeater, that fits well too as a secondary choice.
Also, I've been dying to see a Episode III Clone Trooper model. If anyone is interested, here is a reference pic in case you don't know what it looks like.
Here's a small piece of fan art I found on google of how the helmet might look...
In my opinion in the last pic the visor isn't quite correct. If you look in the first one, the visor has these little curves toward the bottom near the sides of the visor, making it have that half stormie eye goggle look and half visor look. Just thought you should know about that in case you assume that's how it should look. So I'd go with the first pic for reference. The last one was just a additional mention/thought.
