A lot of people have asked about the possibility of ZOS selling character transfers between PC/console (and vice versa) in the Crown Store. But some people have also wisely pointed out that this would have a lot of potential for abuse (item and money duping, trade guild exploits, throwing off economies, etc.). But I think there may be a way for ZOS to sell unlimited character transfers back-and forth without the abuses or complications. So hear me out on this.
What if character transfers applied the "Terminator" principle--namely that transferred characters could only come across "naked," with no money, no items, and no equipment? Only the character itself could be transferred, nothing else. That would seem to me to eliminate most of the potential for abuse and still allow for anyone willing to pay-up to transfer their characters back-and-forth whenever they wanted to. Want to play on the PC for a while, no problem! Just cough up X Crowns. Want to then transfer that character back to a console? No problem, just pay again. But no bringing your money and stuff with you, Kyle Reese. You go naked.
They could even sell server and faction transfers or PS/Xbox transfers the same way.
