Make them to standard. I was involved in an HO club back before internet. Our resident wizard didn't follow standards. A couple members wanted to go to another state to participate in an event and found out they were not compatible. Also anyone coming to one of our events would not have been able to set up with ours.
I was also in a G modular club that set up Christmas layouts in car dealer showrooms, shopping malls, and utility company lobbies. It was always fun and a crowd pleaser.
Hope you pursue the idea. Keep us in the loop...
