[Organizers] Struggling to Revitalize the core post covid

I am in Lawrence Kansas. Since Covid we have consistently had a larger number of new dancers than experienced dancers at each dance. This evening we had a very well attended dance with approx 70 people. I would estimate that at least 60-70% were inexperienced dancers. We are also in the process of grooming new callers and had a callers workshop in March so we are trying to integrate those folks in and get them more experience. I've seen on other posts that a dance can easily absorb about 25% beginners, but we have that formula pretty much flipped. We dance monthly which is a hindrance. Experienced dancers are fatigued of not getting to do more complicated dances. This has been happening for a long time and we need to make some changes so that we have a larger percentage of experienced dancers. Suggestions?
