I definitly don't think the devs will want to enforce that via game's mecaniques so you cann't be sure someone will pay (unless you're in an alliance).
The biggest probleme is that big players usually know by that time that they can have 2 accounts, and will therefor either make a second one or not want one.
and smaller players won't have the rescources to pay for it.
But you're account is actually pretty cool. you're far from any of your alliance's hub, so the receiver would be able to join the alliance he wants, and you have the pop requirement to build a Third city rigth away so the receiver would be able to join the Alliance's hub he wants.
If the devs dont mind that type of trade (they aren't actually losing any player, and you aren't asking for real life monney) , I suggest you contact alliances so that they can upgrade one of their member.
I haven't found a way to change the Email adress when I received my alt (I think we cann't), but don't worry about it as we never receive any notification from Illyriad in our mailbox except for when we sign in the first time.
What would you consider a fair price?
