Unlikely nowadays. It's more likely to be an even split; at least here in Canada, judges don't "punish" spouses for transgenderism. In fact, a highly-asymmetric asset split is most unlikely unless there has been egregious abuse on the part of one spouse.
Anyway, I'm going through a split right now. It's emotionally gruelling but as the joke asks:
Q: Why are divorces so expensive?
A: Because they're worth it.
