It really wouldnt take much effort to get the kids through their Foundation Licence courses. A weekend gets adults through...
In Andover club we used to train Wessex 4x4 members to FL level so they can use 2m between vehicles. We stopped because it was a one way street...we were being used, basically.
BUT, we got them through in little time and I think, to be safe and legal, you could too. If you get caught wilfully breaking the law (and this discussion proves it) you will be rightly nabbed and lose your radios.
Why risk it
