One of the cool things since WFC began is they've limited the redecos and went more towards shared engineering and retools. Hopefully that trend continues. However, looking at the list, there are several possible retools/reshells possible. Leaving aside the hope we all have that these are all done as new molds, if you HAD to have a mold share engineering or be reshelled or you would not get a character, which ones would you want and who would they be based off of? For me, the obvious would be Gears/Swerve off of Crankcase. A reshell, assuming shared engineering could work. I think they would do a new mold, which I would want, but just if they chose to go that route. Blitzwing into overcharge is a no brainer. Arcee into Flamewar. 86 Rumble into Frenzy/Rewind/Eject.
