Is Vriska X Meenah likely to come back, meeting through sleeping and appearing in the bubbles still, or has my ship eternally sunk?

The way I see it it still exists.  Because if John changing Vriska’s death meant that Vriska never was a ghost she never would have formed her pirate crew and John never would have got his powers.  So GhostVriska has to exist because if she doesn’t John wouldn’t have gotten the ability to change the past.  Plus GhostVriska recently underwent a huge design change, most likely so that we could distinguish GhostVriska from Vriska (Vriska).
