I would love to see Nautolan, Togruta & Jawa. While I think that they might reserve Togruta and Nautolan for AoR or F&D, Jawas fit best in the EotE part of the SW lore. I think that they would fit best in the Technician supplement book.

Ithorian and Chaddara-Fan.
Ithorians and their four throats are in age of rebellion.
I wonder if an ithorian named lovelace is inapropriate?
