I use it with K1R and I haven't noticed any problems. Just install K1R later to be double sure.
The only potential is that the crippled Dark Jedi in the Lehon temple may or may not be bugged, but I've been having that problem a lot lately. I think that's a different mod's fault.
WOTOR has a few incompatibilities with some of the UTCs. For example, right before infiltrating the Star Forge a cutscene will completely freeze and you'll be left with a blackscreen unless you reload it, and that will be the frozen cutscene. To my recollection, this was caused by the Bastila UTCs (Any over 002, I think) specifically.
