Consider going with a turbo design.
I just got one and it would be great for Starwars or any other.
two things I like about it.
1) flat sides.. you get into it.
2) It splits in two... Its lighter then my gauntlet cab..
but I would probably redesign the insides from scratch.
Also, I would do a flat seat so you can have two sitting inside when you want...
If you want any dimensions let me know.
