I still don't understand. Please be explicit: what would you want to do that the GPL prevents you to do? Don't say "I want to distribute under another licence". If that's your reason, I would like to know why you would want to distribute under another licence (and beware circular reasoning). If you have another reason, please tell me because really, I have no idea.
Selling (or for that matter, distribution of any kind) GPL software under a different licence is not allowed. If you want to sell, you have to keep the GPL licence.
