I had this idea before but not like this mostly because I don't think any of the swapped out parts would actually function properly if you tried to do it with the toys. Like they showed with Vortex it turns into a helicopter but the arms were swapped out so the place in vehicle mode where his arms would be looked different as well. The chassis actually determines what vehicle mode you go into but changing the arms and legs and stuff does seem to have some effect on that. Now with FoC it looks like they have a better color pallet and something I never thought they would do. The only problem I had was that the color pallets were very limited and especially with the Decepticon pallet all the colors look the same. With WfC all you could do was choose existing characters and recolor them which was fine I never imagined being able to do anything more than that. I just saw a video about the character creation for the multiplayer mode and it's about 100 times better than War for Cybertron.
