Sort of on this topic, a few years ago I was bored and scanning the interwebs and came upon a rather serious scientific argument that the destruction of the Death Star would have destroyed the Endor moon (and all the Ewoks, not to mention our heroes).
Might be worth scanning the net for if you're really, really bored. And no, I have no idea how to find it again, but I swear I saw it once.
As for staying with the Ewoks, let us not forget that they were planning on eating the humans before C-3PO convinced them otherwise (sort of). I can only imagine what happened to some of those poor biker scouts.
