the reason the wei from our world jobbed to leiheng was because xichun released him from his leash (aka loses the heisou mutation since he's not forced to consume the bolus slop anymore)
it gives him back his freewill and personality but he lost most of his heisou powers in return

So long as they're in the main group fighting it counts. I used Heishou + Pequod and it worked just fine. What you can't do is have them as backup.
