Medicom is really into only doing repaints of existing kubs so lets see some wishlists for characters that require only new paint, maybe some slight retooling for hair or something.
Some I've come up with.
Translucent blue hologram Luke:

Black Death Star Droid:

X-Wing pilot Biggs:

Green A-Wing pilot:

Lobot (new communication thing clips over protruding ears)
He obviously would have legs. Professor X is just a good reference for a bald head.
AT-ST Driver (spot the difference)

It's a obvious joke, there is none. I wouldn't say no to a straight re-issue

That's a pretty good basis right there for a 5 pack, it's just a shame they came to an end a long time ago.
There's also the umpteenth R2, C-3PO and Chewbaccas but I've had my fill of them.
Let's see some creative ideas.
