Now that'd be a twist worthy of any daytime soap. I like Quaithe as an enigma, honestly. I have this feeling she'll lose that potency if pinned down - especially if pinned down as a Weterosi. That said, I personally think Quaithe's real asset to the Daenerys story has nothing to do with Jon and everything to do with dragons, which were supposedly originally from Asshai. Well, that and/or Azor Ahai, which is an Asshai'i legend.
