The problem with something like a Jedi battlepack that is geared towards known Jedi (Shaak Ti, Ki-Adi, Plo Koon, etc.), is that anyone who buys one would only really want one pack--you don't want to have 10 Plo Koons floating around in your collection, you wouldn't need 'em all. If they did do a Jedi battlepack, it would have to be full of generic Jedi robe torsos, brown legs, and some generic heads/headgear. Then they could throw in the lightsabers and possibly hoods/capes, and we have a winner.
I loooove the astromech pack idea (not sucking up to Don, either
), since one of my favorite things to do with a large group of generic troops like clones is to set up outposts or something along those lines, including a number of astromech droids (for repairs and such), and mechanics. However, there is one sort of minifig pack I would love to see even more:
A SW aliens pack.
Now, they could do this type of set the same sort of way trading card companies assemble their booster packs--randomly. If Lego produces molds for several types of aliens, does some torso prints and headgear such as twi'ilek lekkus or rodian heads, they could make several different color schemes and randomly throw like 5 aliens worth of minifigs in a pack. You could end up with 5 twi'ileks, or maybe none. But this way, we can mix and match figures reeeally well, and have a ton of variety. We'd see some awesome species we've been waiting for forever to see, and can make our SW universe minifig populations soar. Then they can use the molds in later sets as well, and I'm willing to bet my bum that this would be a great money-maker.
