Um Mira doesn't have to kill Hanharr.
I didn't kill him the first playthrough.
I think Juhani and Jolee should both survive. They are both more important than Dustil and Yuthura.
Also none of the party members you train in Kotor II: TSL are good enough to be Jedi Masters by the time of Kotor III unless its like set 30 years later.
