Even if I have to re-purchase Everything...

Unfortunately, Steam licenses and PC licences for FFXIV, though treated differently in practice in most cases, are listed as the same thing on Mogstation, so you cannot have a PC-specific license and a steam specific license on the same service account. If you really want to have all your characters and stuff, you will need to go over to a PS4 license (or Mac if that floats your boat), since you can own that alongisde the computer licneses. Otherwise, you will need to create a new Service account, buy PC-specific licenses for the game and expansions, use their keys in this new service account and effectively start over.

Yes it sucks, but it is what it is, and we have no idea if they will ever change the license issue to be more friendly to consumers.
