Xerek might join him, though maybe not as a permanent member. I'm working on her custom ship and she may do some things outside of the team (unfortunately, teams don't tend to do well in my experiences with them)
Xerek is technically an anzati brain forced into a droid body, which was later upgraded thanks to another character. However, using the vocabulator and its holographic system. And often wearing either gloves, or having one hand appear cybernetic, she tends to pass herself off as a more normal organic. She's set up as a smuggler most of the time, and she does know a bit about the force, but mainly revolving around telepathy and applying the force to combative reflexes. However, she is no longer able to use it to it's fullest extent due to the loss of practically her entire body. It's something she regrets, but can't change. So she does her best to accept the situation she's in.
If you want her in that is
Talohn Atar
If you're looking for more individual threads:
Rocho Krul used to be a Fel Imperial Knight. He's been a hunter/bounty hunter his whole life practically, and a mercenary. He's one of my more skilled characters. However, he also owns his own carrier and two ships. So there'd need to be a reason he was working with a smaller crew.
If you're a more moral mercenary (only take jobs from good people) I have Kat Kenrid: A falleen. Raised by a mandalorian who saved her from slavers her parents sold her too. Later she leanred she was force sensitive, but she's mostly untrained and has only some ability with it. But she won't tolerate killing or hurting innocents.
