Movie Prime

Was fooling around witht he Bionicle Makuta figure, and after adding and removing a few parts I noticed he looked a bit like movie Prime. I got obsessed with it, spent two days finding all the Lego Technic parts I have and then using them to improve the frame. A few errors and improvements later, here is the end result.
Then I decided: Ah what the hell, I'll kitbash it into an actual movie Prime figure (sadly not transforming, since I don't have enough knowledge of Lego to do that (although I already figured out the transformation)). Next step is spraypainting the frame silver, kitbashing the head, filling the holes, removing excess parts (like the balljoints) and then adding some Peterbilt truck parts.
The truck is the hard part, though. I have a KO Peterbilt Transformer (original mold, but quite a crappy toy), but it's a tad bit on the small side. I might be able to use various parts here and there, but I don't know if it's a good idea using it. Black Arachnis suggested a 1:24 model, but the best we could find is a 1:25 model of 20 euros. Of course I worry that it might be too big, and since I can't check it out in person (online modelstore)...Yeah, I think I will have quite some difficulty with this one.
Oh, the figure itself is quite large: As tall as Primus, and as wide as MP Prime. It also has a good range of articulation; the only thing that doesn't move is the torso itself. Only things I need to take care of with the frame is some stability uses with the lower legs, which tend to collapse under the weight or bad posing.

EDIT: Yeah, I know, crappy pic. And the legs are mostly hollow because they're going to be filled with truck parts, like with the movie designs. Likewise with the chest, which will have the truckwindows added later on.
