Hello there!
Maybe someone post something like this before but i didn't found.
I love the Imperial Scout Trooper and I like to see them as a kind of snipers. Perhaps within a Endor expansion with Rebel Commandos and... Ewoks? Ok, better no Ewoks. 
Also it would be great to see Imperial Army Troopers or Navy Troopers. Could be a spaceship/-station expansion. But they should be weaker than Stormtroopers and then they are nonsense. 
May the force be with you...
