Yes !! Apparently there are a lot of humans things (like architecture) that was inspired by the elves. So, yeah, this makes sense for the crowns too ! People have forgotten the origin of the designs. I like this idea so much !!

Also, for Flemythal and Andraste : Flemeth told the Inquisitor that she sometimes helped the fate, it would not surprise me that she helped Andraste at one time. 👁👁 (And lore speculation is the best thing !!!💖)
