Oh boy, a 1v1 challenge from Lyraeus for Vassal! How could I say "no" to that lose-lose scenario?!
If I win, I have to deal with a potentionally rage-complaining Lyr offering a ton of reasons and explanations as to why it happened but shouldn't have. Or else I lose and have to endure the gloating. Neither seem worth spending three hours.
Just do a game with someone else that is Vassal savy and willing to spare the time:
Have them play something like a basicTRC Mothma Swarm, with 2400s sprinkled to taste. This is the sort of match-up that makes B-Wings a big liability.
Sounds like you have it all planned out. Whats the problem?
