Well I'm pretty sure (although not positive) that like many other special bonuses such as crit hit rate% among other things apply strictly only to that weapon. Therefore the TP bonus would not apply unless using a hand to hand based WS outside of Dragon Kick while using Footwork. I think I'll buy a pair and find out for sure. But this is a clever idea, and I'm glad you brought it up.
Also, MNK/DRK is incredibly fun and great at pushing out big numbers real fast but unfortunately is only effective if you have someone cure bombing the hell out of you, as with souleater's % based reduction with super fast attacks of MNK, it's power quickly depletes with your HP as well.
