If you don't mind losing game shape for a couple of games (and possibly losing fan support if they're gonna be tough) and you want to go for the win it's probably not that out of reach. His 1 play that is far and away better than yours has played almost 90 minutes so he will probably be sitting. And several others of his team have got ~60 minutes in so you have a chance. He may look at you as just a small lump and play TIE, fully expecting to win handily regardless of who you put out there.
It really all depends on if you think the potential 50k is worth losing some of your best players' GS or trainee minutes over.
