In my experience, the only meaningful difference between the non-Fairie races, aside from the occasional race-specific piece of equipment, is starting stats, so I see no reason why it shouldn't work. I note that there is one rather nice weapon, of which several are reliable drops (a certain powerful enemy drops them), is Mook-specific and usable by rangers.

Try it! I don't see the party having any issues during the game.

(Interesting note: Notice that your party has, in addition to the Bishop, one hybrid caster of each type?)

Looks perfectly reasonable. Only the Samurai has to do some work I guess. You should probably push Senses to a reasonable value (around 45-50) to make his dual weapons and critical strike rise reasonably fast, and he will probably never have a lot of Spell Points (low PIE), but otherwise this looks fine.
