We could use  a hacker  guy. We could also use a thief: a guy capable of quietly picking locks and breaking into areas. Though lockpicking and sneaking is  also a skill that would be common amongst many outlaws.

That is what Enalais was going to cover with his black widow type. Hacking/Slicing depends on whether or not he has it.

Caboose, I'm not trying to steal the explosives role or anything. I just can't think of what roles that aren't taken are.

You can copy a role that someone else is doing... I mean the likes of a tank style role or assassin/theif role we can double up. The only two I'd say shouldn't be doubled up would be the pilot and the sniper.
