you might be better off taking one of the toons you already have and starting them out on PvP.
all of those classes you listed as having are all in very good places right now.
it would also be a shame to start leveling a new toon, only for bioware to nerf the crap out of it in a few weeks.
Yeah I thought about that too. I'd hate to level a class for pvp then in the end get nerfed like crazy. But, I'm wanting to level a new toon. Kind of tired of the ones I have. I haven't level'd a new alt in probably 4 months.
