I think this is generally a good idea. However, there is a reason why one finds few "professionals" in forums like these. These forums are more like self help groups. Everybody knows a little bit, some know more, of course, but often, we don't really know what we are talking about. Yet, in the end, everybody learns something.
Professionals (scholars, coaches of professional pianists and professional pianists themselves) usually will not waste their time participating in such forums. There are even very few music students here. I doubt this will change, even if you would contact such people and make them aware of this forum. I see us essentially as a bunch of amateurs who help each other out, but I do not think this forum qualifies as a serious venue, and that's just fine with me.
