Also, you guys are pretty good at Touhou naming in Disgaea, but here's some more ideas.
Reimu and Sanae = Ronins (Look at her. LOOK AT HER.)
Just about any regular magician in Gensokyo, Koishi, and Flandre = Star Mages (Mega Star was what I can imagine being Flan's blowing up ability, and Koishi is pretty neutral.)
Remilia = Hero Female (Blue hair and A rank spear expertise. You can't resist.)
Chen and Orin = Nekomatas (Actually, the female martial artist reminds me of Orin...)
Youmu = Warrior or Ronin
And building on what you reccomended...
Mokou should have fire spells, but she'd be better as a Spellknight or Ronin.
Patchy could also be a Galaxy Mage, but Satori is definitely one.
Kaguya also looks like a healer, but she'd need Galaxy Mage first, I suppose...
Letty can also be an ice mage.
