How much time do you currently spend working/ week? It the purpose of growth outside of money? How much money do you need?
I think you have honed in on your niche very well and growth for growth sake may dilute that. It wouldn’t surprise me to hear that you stayed small and were able to make more money than you thought possible by sticking to your tribe.
You could create small batch stuff with a satoshis reserve label and sell it for 10 x the price of last round. I don’t know just random thoughts. It’s a good problem to have.
