I suppose, but they'd not be very trusted. It's very likely they'd be passed over more than once due to it. Instead going for the less experienced, but non heteromorphic guilds. So as a buisness it would be stupid not to cater to your customers base wants. So far I suggest barring people as its leaning towards being completely heteromorphic. As I've not seen more than two not heteromorphic characters  besides mine and yours. 

If I'm wrong about there being more non heteromorphic characters I apologize. I also apologize if I come off as the bad guy.
