Christopher Pike, my assumption is Vina’s return would be best if it happened in Star Trek: Strange New Worlds, which is currently in production on Season 1.
Melissa George confirmed that further Star Trek conversations were had, and not only about simply returning as Vina but seemingly for a larger presence than what her brief appearance allowed in Star Trek: Discovery.
While she could obviously return to that series in some capacity, it’s not the most likely eventuality.
Giving Vina a larger role in that series would make sense, given Pike learned of his eventual fate and future with Vina through wielding a Klingon time crystal.
