Mara would be great. Padmé in her skin-tight white outfit from Geonosis isn't an idea I'd scoff at.
Yeah, the recent trend at Hasbro towards cutting more corners than a bank robber fleeing the crime scene doesn't surprise me when it comes to these 12" figures. Depending on how the Vader looks in the box (the line is supposed to have three or four characters total including an Episode III Obi-Wan) I might get one and the Clone's always a possibility just for the heck of rounding out the shelf display, but nothing about these things excites me.
When a green window box is the coolest and neatest thing about a product that's never a good sign.
