The area of this hobby where there is great potential to gain pattern participants, IMO, is with drone pilots. In Texas, the drone racing league is huge, and full of competitive and young individuals. When they burn out in a few years, (and they will), they will look for some other outlet. I am always available to answer their questions when they approach me, and suggest that if you have some racing drone pilots in your club, make yourself open to their questions, and show them another type of competition.
