Hi! The twin question was asked on my behalf, so one just in case clarification there, please. :)

What if the twins are not appable as separate characters? The pair I play are treated as a unit in world/plot/game mechanics, and personality differences are superficial (favorite ice cream flavors and the like). They are never physically separate and never act/appear independently.

In case of canon familiarity, I speak of Tweedle Dee and Tweedle Dum from the Alice in the Country of Heart franchise.
