I had the chance to zone out at work today and draw up a simple but effective stance/special system based off the elements that would certainly be "an actual sizable increase to both monk DPS and survivability with a non negligable increase to their utility" what with the utility stance and tankish stance. It was similar in concept to the animal stance thing I did way back with special attacks changing functionality, but I still have no idea if that is even possible. Moreover, I do not forsee any serious class redesigns with 3.0 on the horizon then Combat Abilities entering into the mix and other better fixes available. Even worse is that several people will defend the slow and clumsy and not-very-interactive combo system because they cannot differentiate what they get with how they get it
All and all it feels like just waiting for 3.0 and focusing on other characters in the meantime is the way to go.
