Can't wait to find Vehicon and Knock Out.
[Try to get this Grey Hulk Crossover and you can use its Hands and Legs to upgrade Superion.
I have the Fansproject kit but this is a really great substitute for those who couldn't find it. Do you have to modify any of the figures or can you just pop off the parts you need and peg them on?
The only thing you have to do is put a screw hole in each of the four energon stars that the limbs come with. You *do* have to be careful, and a hand drill is apparently recommended, but it appears to work quite well. I found a pretty nice tutorial that explains it. I don't have any of these sets, but if I can pick up a Crossover Hulk, regardless of color, I'll start poking around for one of these sets!
