The real question is which one would stop running his running mouth first, and finally get on with it.
System Lord: "Kneel before your god!"
Sith Lord: "You will now know the power of the Dark Side."
*several minutes later*
System Lord: "Sith, cree!!"
Sith Lord: "I sense fear in you."
*about an hour later*
System Lord: "Bwahahaha grrrr arrrd, cree!"
Sith Lord: "Mwuhahaha Dark Side!"

I haven't watched Stargate SG1 in a while - so your "Sith, kree!" brought back some pleasant memories.
I think the 4 or 5 person SG1 team will defeat the entire SW galaxy singlehandedly. And Lord Vader will be left going all "Noooooooooooooo" while O'Neill will probably say "That's so Gay!" (and add a "Not that there's anything wrong with that").
FYI - I'm not gay-bashing. Just referencing some of the fanboy posts after the release of ROTS. (And Seinfeld)
