So after experimenting with a few paper prototypes I've come down to two options
Option A at the top is voyager class, and closer to a crossover SUV. As you can see, this transformation borrows a lot from classic Arcee while also giving her a booty. Titan masters would have holes on her thighs, and fit no more than 2 in car mode. However, the drawbacks are 1) a lot of moving parts and hinges 2)a poor alt mode that most likely will sacrifice a lot of it's shape and design to make sure all the parts fit together in robot mode
Option B at the bottom solves a bunch of these issues (Leader class, far fewer moving parts, able to carry 4 titan masters on a floorboard that makes her "spine) But suffers from a very non-arcee transformation (but fun all the same). Oh, and I think I've flipped the door panels on her legs by mistake.
I don't have the time or the money to invest in scratchbuilding (possibly 3d modelling) both, so I need to decide which to do.
