When I had a similar conversation to the Nimrod mates wrt landing an almost empty aircraft on the short 3900' runway, I was told that to RTS will not be made flexible even for a final flight as these days nobody takes additional (& documented) risk. The pragmatic view would be to wait for an easterly wind to avoid approaching over the railway embankment, and I dare say that in practical terms it could be done: MAA approval would be a different matter.
