If I were still in England, I would structure my agreement to conform exactly to the Blue Book. Then I would have no problem deviating from that agreement. 2♣ bids come up rarely so unless SB wants to keep a couple of years worth of records, he can't claim my deviation on any particular day constitutes an illegal agreement.
I like it!
EDIT: However, I think that I will use "20-22 balanced or GF; the latter may not comply with the current EBU definition of 'strong'".
However, I will at some point experiment with EBU compliance, because I think it will be fun to experiment with using my strongest bid to open suitable Weak NTs.
