Don't think you could to do that in my state because we have a deadline where each gym must declare what level each gymnast will be for state qualification, and it is the same for all levels and prior to all levels states. Think it's mid February and our state meets start happening in March. So if you declare yourself a L6 in February, that means if you do a states (you still need to qualify), it's got to be L6. You are still allowed to go to meets and compete as a L7, L8, etc., after that February declaration, but you aren't able to go to any other state meet besides for L6.
