Hey [@TaintedMushroom], what do I think? (Bear in mind, this is just my own opinion, I have not discussed this with the other two current crewmembers, and I welcome their input!) I think Bounty Hunting is a very personal, private endeavour. I can't really picture a time when a Bounty Hunter wouldn't just have their own ship for their purposes, rather than relying on the diplomacy of people they would seemingly have to agree with or answer to. 

Now -- in the rare case when a Bounty Hunter might ned to blend in, to get closer to a Mark? Sure. Hire a smuggling vessel. Or if an ex-Bounty Hunter wanted to go 'straight?' Maybe a crew would be an easy way to leave behind such a vigilante lifestyle. 

I don't generally think that A Bounty Hunter would agree, or have an entire crew's best interests in mind when taking on jobs. It would also mean that a Hunter would have to share their take with others, which seems unlikely. 

Now, as a "guest spot?" Or as a recurring rival to jobs? Absolutely. And the shape-changing races? I have no issues with. But that's my $.02.
