All that stuff is already there in spades, and has been since I was zooming around there in 1983...
Ever had a close look Cap'n? It's a 'bare base' - the stuff that's there is very basic and only intended to support short term deployments. It would not support a full time operation of 50-plus aircraft. Most of it has been there since the 1970s, if not earlier, and is probably riddled with asbestos. I'm guessing they'd have to pull the whole lot down and start again...
