That is indeed interesting and welcome insight into SRG thinking on the subject.
As for a trade of FAA AD license, I don't believe the FAA license would or should be accepted in Europe, it is far too US specific; that said, perhaps some exemptions from parts of any new requirement might be given and generic subjects- Met theory as an example, but subjects like air law and regulations form such an important part of a FOO/Dispatcher training that a straight swap would be wrong.
