quick idea.... I think Jin, Ptitvite, Frenzy Rumble or anyone of the countless great kitbashers should do this one. I don't have the money for it or the testicular fortitude yet.
I think the biggest problem here is scale. I'm pretty sure Ratchet's a good deal bigger than Deluxe Brawl, and I don't even want to think about Astrotrain next to Blackout. @.@
Yeah, you have two voyager limbs on the left side, and two deluxe limbs on the right side. He'd have a heck of a limp.
i'd suggest landmine instead of ratchet and maybe remove blackout's backpack andod it to be a hand held weapon.
There's also the fact that Leader Prime is MUCH bigger then all the other figs pictured there. I think the only way this could work would be to use Landmine, Dlx Brawl, Blackout(w/o backpack) and Dreadwing (keep it all movie based) and use Voyager Prime as the body. But even that would be rough to pull off.
Well I was going to say scale issues (I don't think black out is the same size as Astrotrain though you made it so, etc) but looks like everyone else pointed it out already.
i was thinking of making one out of Voyager OP, and the target exclusives signal flare, air raid, crosshairs, and skyblast. maybe you can try that?
