Have you spoken to any planners, a quick search for similar applications in other LAs might be a useful thing for them.
There's a Royal Institute of Town Planners, they probably have a magazine you could advertise in (but equally that might get you blocked, idk).
RICS people could probably use the data too? I guess it's useful house-buyer info; houses in the vicinity had successful loft conversions, say.
On the data side - it's something of a moat for you now, but I could see you being successful with FOI requests. An MP might be interested in championing open data access.
