This has all be done before, hence the short runway as is. There will be no road closure and there is no way the tombstones, church or anything else is going to be moved. Rochford Council put this to bed 2 years ago and anyway the costs to move the church were prohibitive. Much of this has been covered on previous threads. End result despite all your enthusiam is a runway that is to short. Finally as someone who also lives part time in SEN most of the locals and do not know that the airport exists and care even less, on a good day STN is 40 minutes away, LTN 70 minutes and LGW about 90 minutes. I hope that I am totally wrong but its best chance is as a housing estate provided much needed revenue to the Council.
