To make race and class list complete we would need - a short race like halfling, gnome or dwarf - a scaled race, which means dragonborn.
As for classes we are missing - Bard - Monk
Helia would be obvious, although I have nit orogressed into the story enough to tell how much Halsin is using her concept or if she would be a bit too similar to Astarion That would leave a dragonborn monk.
