If the figures are movie-accurate, Luke wouldn't make a very good army builder since he's pretty short for a stormtrooper.

I'm afraid if these were offered as yet another screen scene, they'd be in poses as dedicated to said scene as the Trash Compactor sets. The last thing I want is a Han that only looks good with his feet on an Imperial console. It might as well be a PVC.
We'd be better off with individually carded figures if we're really interested in both authenticity and army-builder appeal.
Han could use a new, definitive Stormtrooper sculpt with oodles of articulation, removeable helmet, blaster and binders.
Luke could come with similar articulation, removeable helmet, blaster, and commlink. Give either one of these guys a SCALE mouse droid and I'm tickled pink.
I'm all for an Imperial ante room, but I'd prefer a screen scene with Artoo plugging into the Imperial network while Threepio nervously confronts a snooping Stormtrooper.
