I think Marluxia was smart enough to know whether or not he could really take on the rest of the Organization. It's not like he manipulated Sora and Naminé it on a whim, even if we do say he disliked getting his hands dirty - he was willing to do it and did it on several occasions.
He would had been the perfect Org XIII leader, at least than how Xemnas was portrayed. He was like a second XH only screaming out NOTHINGNESS!~
