It's totally fine, I was a bit worried about the alchemist, but I think I could easily retool the duelist. I was originally thinking a fencer, but I could easily see him as just a one-on-one fighter with a bit of flourish and a long sword. And a big hat, because he can't be fancy without a big hat.

Then again, unless we already have someone filling in a "healer" role, I could be a barber-surgeon... Because barber-surgeon. Actually I think I might do that, the more I say barber-surgeon the more I love the idea of it. No idea how effective a barber-surgeon would be, or if that's even the right time-period, but I'll do some more research and get back to you.
