SWEETness... 4 pages already, lol.. I'd love to help on this, I was actually thinking about this last night, one thing I'd like to see done is make sure we have someone incharge of certain things like the certain "armies" or types of "people" we'll have populating the diorama.
One thing I'd hate is for thngs to get started and when people start submit, you get 100 people sending you clone trooeprs with plaint splotches thrown on them...
I say get a couple "Team Leaders", have them incharge of certain factions, and set limits..
I'm not too versed in GAR military procedures and specifications(though, I have a insider somewhere that has some stuff in it)... but I'd like to see a cap on the amount of troops.
I'm all for the time frame between RotS and the OT, and if you think about it, it'd be perfect cause of what they'll have in store for us at C4(the new animated series and the live action series)...
I'd be all for helping out getting things started and sorted out... I'm a stay-at-home-dad, I only work part time on Tuesdays and the weekends... so I'd have the time.
I like Chewies idea about Owens work.. and I'd be all for chipping in a good $50 for it.. but like someone stated, I think there should be a cap on that.
I think before we continue to throw out ideas, we decide on the 2 main things...
TIME PERIOD and PLANET.
Once we get those settled, I think we can go from there...
How about a couple polls on the different boards to get that settled and then we can move on?
I know it's still early, but one thing I think it would be nice to decide on is what phase of Imperial armor the troops will have... I think it should be consitent...
Should it be Phase 2 as seen in ROTS, or the helmets the Stormtroopers wear in the OT? I'd love for them to have on OT helmets, but realize getting Phase 2 troopers would be a lot easier. Plus those are really damn popular.

You did some hybrid troopers, mixing them between the prequel and OT... i think that would work beautifully for this.
That way w arent just repainting clones, we are transitioning them. Any Stormtroopers would be the "first batch" of these new model troopers.
I think this could be a good idea.. maybe we could all agree on a set look, that way they look semi-uniform... lol.. amd maybe have a couple stragglers off to the side...
I could see a Jango series, all old and grey sitting in a cantina drinking away his sorrows, lol.
