Its been suggested few times before, but an OOF bike/alternative vehicle meet. Maybe try and make it into a little road trip if possible? Perhaps not Scotland as quite a lot of time would be needed for that, but do Wales?
I know Daz was interested, Albs get some use out of your bike? Bruce? Long haul for you, not sure if you can get your FJR down south by other means?
I think you are forgetting that many riders, rightly or wrongly, will want to go an awful lot faster than you. To give you some idea, as you really seem to be struggling with the concept, I am a very slow rider

. You are probably looking for riders happy enough to poodle along, and be perfectly happy sitting behind traffic.
IMHO, if you end up with a group where some want to rag the thing everywhere, and make short work of traffic, along with the poodlers, everyone will be frustrated, as the fast riders will get frustrated constantly waiting, and the poodlers will get frustrated, maybe embarrassed, not keeping up. And this is when accidents tend to happen.
Again, to reiterate, whilst you may think that GS is quick, it really isn't. Its quite agricultural. In that rider scale from Poodler to Fast, just so you know, IME, I'd put myself at the upper end of Poodler. I feel I have to drum this home, as you've told me before to take it a bit slower.
Hope that makes sense, and in no way a critism to your/mine/anyone's riding style. Just ensure you get like minded people from a riding style point of view
