Well, you could/ can do that with FFXI. I imagine SE disliked that so they designed this system specifically to disallow it. That said, there are sometimes Steam sales and the like on the PC version. Unless you need to play on PC because you can't / don't want to use the PS4 for that anymore I'd probably wait for one of those if the cost is a deterrent.
