Nev Map without combat poss

Hello

I always want all the maps to be larger but I am a particular fan of the Nev map and that part of the world where I've actually holidayed. I know that devising a map that can be fought over etc can take a great deal of time to devise but is it possible to at least extend the map with the desert terrain toward, say, Grand Canyon, or South West toward Edwards, Utah an California? For a hard core flight simmer just the joy of flying good military aircraft over these areas would be great.

Thanks

Neil.
