For Botcon '09 they redecoed Cybertron Sideways (and gave him a new head) for Timelines Scourge. I don't think Sideways was the best choice. Thunderblast, or at least her boat shell, would have been infinitely better. Maybe use Energon Sharkticon's body with TB's shell. But come on. Thunderblast's boat-hull "wings" give her a strong resemblance to G1 Scourge and his Sweeps. Not only that, but G1 Scourge's altmode was very boat-like. And while TB's robot mode main body is unquestionably feminine, since she's a shellformer switching it with a more masculine body of similar size would be a fairly easy task. Just add Scourge's head, and you're done. And for BotCon Elita they should totally have put Thunderblast's head on Override's body. Override is rather feminine if broad-shouldered (The cockpit gives her a monoboob like Arcee and the Female Autobots, and just look at those legs. And her animation model is more slender, so...), and her car mode is closest to the little that is seen of Elita's car mode. The icing on the cake is they considered Override Elita-like enough to repurpose her GTS repaint as Shattered Glass Elita One.
