Strength to your elbow, Tony.
I recall a bunch of enthusiasts tried to get something similar to Leon's idea off the ground at Swanton Morley after RAF left in mid 1990s - combination of heritage / re-enactment experience and a centre for restoring, maintaining and flying historic aircraft. Didn't come to anything. Think the Army moved in, in the end. But the idea is great, even if hurdles are massive.
I'd certainly pay good money to take my young'uns along to see what a WWII flying station was like - or a decent approximation.
Good luck.
