Well Kes can still teach him Ataru even if he doesn't still use it, as Ataru mostly comprises of acrobatics, and he can teach you that, and teach you Makashi at the same time? Is that cool?
You want to do a little training duel between Xeshan and Tuxmeth?
EDIT: I see Xeshan doesn't have any form. What form do you wish for him to have, Makashi, Soresu, and Djem So from Kes, or Djem So just from Tuxmeth? Maybe he can lean some force powers like Force Stealth?
I think that may be a remnant of the past. I personally look at content and quality. That might also be an error, meaning posts rather than pages. Hard to say.
