Again, we're not even talking about a number as big as 10. Seven at the most, but I'd be fine with six (Tatooine, X-Wing, Hoth, Bespin, Endor, Jedi). I could live without the Stormtrooper disguise and Endor is even questionable.
But let's stick with seven for the sake of discussion. Everyone might not want all seven, but EACH outfit of the seven will have MANY more fans than any prequel Jedi or cantina denizen with no lines. No one is forcing anyone to be a completist and SS would be crazy not to allow for a good number of multiples of the main characters, as long as they're totally different outfits (though even saying that I wouldn't mind another ROTS Anakin with messed up hair and better paint apps.)
