Romy, it sounds like you are well into this, already. We used to use extremely sheer silk with our "secret" doping formulae. The key is to keep it as thin and flexible as possible. Today, I would look for resin/glue with "fibers" in it to bridge the rip itself. Maybe the "dope" with silk or fiberglass fibers mixed into it? I think they do make a glue from crab shells, or something like that. Old-style "hot pot" furniture glue is of horse hooves, and it should work, but you would have to be careful not to glop it. Likewise, rabbit's foot glue. A good bond to the edges of the tear, with fibers bridging and connecting both sides of the tear, with no extra layer of material over the surface of the cone, would be ideal. Bridge the gap and back the repair with blue tape or "architect's" tape on the side opposite the repair until the glue sets up, then remove the backing.
Orange County Speakers is the Southern California outfit that does a lot of the pro gear, and they also sell some supplies for all kinds of drivers. Also, they have been around for a while, and they know people, including the kind of weird-os you might want to contact. I suppose we don't generally look to pro gear for tone; but it's a lead...
Don't forget Steve and Rich, aka, The Cogent Boys...
