On topic, 3 variants.
One:
- Malgus after DE Luke - pretty much goes either way, or small nod to Luke; incredible fight either way,
- Vader after Jaina, where I would honestly give Jaina the nod; Vader is ~ Kenobi for me (unlike Anakin, who's the clear superior), while I take Jaina as slightly better combatant,
- Krayt goes after Kenobi, where he probably wins narrowly.
In this case the fight goes for the Sith (given Krayt-Kenobi is probably the most assured fight), but narrowly, very narrowly, and in the event Malgus falls to Luke, Luke then is too much too handle when he is free to interfere, and the Jedi can win. All the fights are going to be so narrow it is truly likely.
Two:
- Malgus vs. Jaina Solo - Jaina doesn't stand a chance, Malgus wins everytime,
- Vader vs. Kenobi - which can go honestly either way,
- Krayt vs. DE Luke - where Luke wins in a great fight.
It's basically a toss-up. Depends who wins first; Malgus or Luke. Money's on Malgus though, and if he joins Vader, they murderslaughter Kenobi; if he joins Krayt, they dogpile Luke. Nod for the Sith.
Three:
- Malgus vs. Kenobi - Malgus slaughters,
- Vader vs. DE Luke - Luke slaughters,
- Krayt vs. Jaina Solo - Krayt wins in a very good fight.
Again, toss-up, depends who slaughters first among Malgus and Luke.
