I used to think that WotC had Star Wars licensing locked up, but then WK announced their constructible game. So sure, Mongoose should look into this. But I wouldn't bet on them being able to get it.
I would just go ahead and make SST:Evo house rules for them. (Only Imperial Stormtroopers Are So Precise: Stormtroopers lose their four highest damage dice (determined after rolling) when firing at any unit that contains an officer.) The Evo system seems eminently suited for this.
