Are those names drawn from the sources I think they are? The last two kind of tipped me off. If so, I heartily approve. If not, well, they're still fun.

You have enough dorfs here to make a mix of whatever dorfy stereotypes you like, so I think that you should take advantage of that (if you think that they'll have enough screentime to even display more than one or two traits).

Do you want them to all have the same class (or at least related classes)? Or do you want them to be basically an adventuring party unto themselves?

Hmmm. I could see each one being focused on a different ToB discipline. That might be funny. The odd discipline out? Stone Dragon, the dwarfiest discipline of all, just because.
