Well, Han has to stay 18 squares away from a JH, the Officer, AND the Shaper in order to not be insta-killed.
So, definitely going to be some trickiness with it. However, the only map that will really kill this squad is Mustafar, which is why Nom Bombs saw very little play at GenCon '07 anyways. Hopefully, with a little more balanced map situation, that should be much of a problem.
Only thing to watch out for....Flea, your JH's will only attack at +9 for 20 under Disruptive and against a non-Force user. The Shaper's SA doesn't add an Attack bonus.
So, as most of us have identified at some point, these guys are going to have the toughest time against Kyle JBM. However, the fact that he's a Jedi, and he can't use Block/Riposte on them, their +13 w/ JH for 30 damage w/ the Shaper's SA should kill him quite quickly. Especially when it will take at least 2 rounds for Kyle to kill just one of them, and even then, only if they fail one of their Crab Armor saves.
