Okay, so both games I play Mako in have a Bolin already, but I know the Mako at highseas and they'd probably love a Bolin, even if you took them from an early canonpoint.

Can't say too much about the premise except that you get to be a pirate, and being a pirate sounds like something that Bolin would excel at pretending to be. It fits his crazy "actor" skills.
