Katarn and Saba are arguably superior to any of the duelists of the TCW team, Caedus stated he'd have a difficult time with Saba in a fight.
Jacen could defeat his mother or Ben without trouble; Saba, with difficulty.

I think Q or Newguy stated she defeated Corran in a match, was faster than Ben Skywalker, beating Kenth Hamner. She's a formidable duelist and likely above Tiin, Fisto, Ti, Kolar and easily Mundi.
Katarn is somewhere between Kenobi and Koon in terms of skill, I have him marginally above Koon but slightly beneath Kenobi.
Assuming Jacen defeats Windu (which he can), Kenobi falls to him next or Saba and Katarn pick off the next best duelists down the list.
Mara is superior to Fisto, Jaina vs Ti could go either way, Corran may or may not lose to Kolar, and I'm not sure who would win between Mundi and Kam
Overall assuming NJO can manage with losing Corran and Kam I think they have a shot. I think they can do this for a majority
