To be fair, Luke stomped an incredibly conflicted Vader in ROTJ. I doubt the outcome would've been the same had Vader's doubts in that moment been erradicated.
Vader wasn't that conflicted; it's even noted he was willing to kill Luke if it came down to it and that he exhibited "more deadliness" than ever before or some such sh!t.

Of course that's a possibility, but so is that they will manage to take Luke down with ranged combat.
I suppose it depends on the distance, but assuming Luke closes it swiftly, Dooku and Exar die.
