Ah, ok. I was thinking looking at the photos that it would lend itself to having some kind of guest accommodation - a basic hotel if you like - for people attending events, but given the description that might be the part of the building that is beyond repair. It would almost make more sense as an arts retreat of some kind. Either way maybe the thinking should be that this is a destination for people to visit from both locally and further afield rather than just a local resource.
There's a big problem when it comes to reusing redundant church buildings. 'Turn them into arts centres' rarely works, often because of the problem you cite - there really isn't the demand for them in rural areas. And in city centres there can be a dozen or more barely used churches, very often uninteresting ones. They can't all be arts centres and community cafes.
