I ain't got no skillz, but I've got some ideas/suggestions for anyone looking for a challenge: 1) Grimlock made from Energon Jetfire (I actually bought an extra Jetfire and the T-Rex vs Leonardo TMNT set figuring I could do this - I couldn't). I figure a Rex bust mounted on the front of the jet could flip back much the way G1 Grimlock transforms, and the arms can kind of roll back out of the way (and has retractable/flippable fists) to make decent dino legs. Not sure how to go about handling the legs/tail though, but you guys are more creative than I. 2) G1 Razorclaw out of Cyb Prime. Swap out/cover the cab of the truck with a lion head, and then, well that's all I've got. 3) G1 Divebomb out of Cyb Leobreaker. Should be easy, just change the lion head to that of a hawk and strap wings on (which can then be strapped onto the back of Cyb Prime/Razorclaw). 4) Sunstreaker from Mach Alert. About a year ago CVP was selling some cheap transforming robots that had Sunstreaker's head. Glue this over the Mach Alert face (some sanding may need to be done), remove chest and replace with a thinner chest plate (new head too wide for old chest to flip over in alt mode), glue exhaust pipes to shoulder sections, and repaint. 5) Jhiaxus out of E. Jetfire. Uhmmm, good luck.
