The mods will have to confirm you're not officially breaking rules. I would message Bat or Mama Bear to double check.
I would be hesitant as the buyer as logging it would likely log two different IPs for the account in a short amount of time. I don't know if anyone really understands TNT's current method of monitoring accounts, but this would likely flag it.
If you're open with your buyer and they accept the terms, then the liability falls on to them.
