Rarity, in this verse can stay almost completely the same.
I did have this idea for a character trait that she’s insecure about her age. But in the opposite way.
Enutrofs, if you’ve ever seen them, always look old like their god. Young ones exists, but they never seem to be on the surface. So I speculated the younglings train and dig away underground for a time until they reaching maturity, which probably looks middle-aged by regular standard(or until their pockets prove deep enough to buy their way out).
My thought is that Rarity, often seen as the most mature of the group, would still look reasonably young and conventionally pretty, implying she was quick to get out of the caves. Which wouldn’t be a problem until she meets another enutrof. Since they respect age almost as much as gold, someone like Rare, out and about with her friends and trying to get her business going would be seen as too young, ignorant, air-headed, and even get called ‘half-baked’.
What do you say, a good addition, or too out-there?
