Saintsman Assuming you are serious, the answer is NO. For the cabin crew it is not worth their job to do that.
Whilst there may be some carriers in some corners of the world that might consider it, I have to say I doubt it. Don't forget, you would have to pay off ALL the cabin crew as your change of seat would be obvious to all. So you have to hope that all of them will be ready to take the cash and none to spill the beans?
