Mechanically yes, narratively no.

Maybe I focused my answer too much on the mechanics and not on character concept, but for a one-shot game that's what I would personally look for: to try out some mechanics I haven't yet. Certainly, a battlemaster doesn't have a huge narrative appeal. But I would keep the cool character concepts for a campaign that lasts longer than one evening!
