I like it.  There are a decent number of 40k/WHFB nerds here who would likely be down.  I know JB hosts a lot, as do Selune and BCTheEntity.

I'd be down so long as you don't mind a Ratling.  Sneaky little dude, Long Las and traps/sabotaging stuff.  I forget his name but I'm sure I've got the CS somewhere.

I've always liked the lesser powered groups of 40K and Rogue Trader in particular as they strike me as slightly more Indiana Jones-y.  Orcs are probably my favorite potential enemy, but tyranids or some like Chaos maddened humans are fun.  Anything really.
