As a former LTMA controller now in semi-retirement further north, I laughed my little socks off when I saw Creaser's question!!
Personally, I think its a great idea......
Creaser, if you are serious about this, you may want to speak to someone with a current professional aviation background who can explain a little more about the airspace involved and the notification requirements for non-standard flights within CAS.
You ask "Is there much chance?". Without proper arrangements in place, I think that the answer will be November Foxtrot Charlie (= no chance).
