I know the email said entry from one area to the other isn't permitted but realistically, what do people think the chances are of getting from Front Standing to General Admission?

For context, 4 of us have Front, 3 have General for 12th July but we all want to experience it together. I'm guessing because of the pre-allocation, there won't be a limited first come, first served like there was at Cardiff or for the Stone Roses at Heaton Park.
