I think a 1/6th scale Ronto would be awesome.
When I first saw the creature in 'A New Hope' (Special Edition Version) I thought it was the coolest thing ever and really welcomed the additional footage. The Jawa falling from the saddle was classic. I still have my original 3 3/4" scale Kenner Ronto with "bucking" action. Power Of The Force rocks.
The Jawa would need to be removable/articulated, with light-up eyes. They could use/modify the new Yoda body they recently developed.
They would also have to make the Jawa available for purchase separately, perhaps in a two-pack. It would be killer to have a little gang of five or six Jawas in my collection just waiting to creep up on some unsuspecting droids.
Epic.
