I don't think two baners would count as bastard.
But it would be unusual.
I could see it as
1) 2 baners to offset wolf power vs. mostly vanillager
2) 2 baners (as far as the baners know) but at least one of them isn't really a baner / has inconsistent powers
Though since bladescape didn't really claim baner, I think it's more likely there's just 1 baner.

Too little discussion, so let's change a 3/1 vote to 2/2 and see what happens.
