OK, they still could do:
Ronto w. Jawa (I'd buy it, but it wouldn't be my first choice)
Eiopee (w. who? I want Shmi Skywalker in a 12" one way or another)
Jabba the Hutt (w. Oola would rock! Bib's been done, same w. Slave Leia)
Bantha w. Tusken Raider (I'm so there!!!)
Nexu - this could sell on its own I think
Orray w. Geonosian Picador - this could rock. The cart could make it better!
Reek - This could be really cool if you could put all 3 heroes on it.
Massif w. Tusken Raider - maybe... I'd prefer the Bantha. Both?
Are the Rancor and the Acklay getting way out of control???
I could see the Rancor before the Acklay, but man would either of them make a "Christmas item!!!"
