Why not look into roaches? Something like dubia roaches (if you're not in Florida) is a great feeder because they don't climb smooth surfaces, don't fly, don't chirp, and don't smell, so you can keep a number of them in a plastic storage tub with egg crates and they will breed on their own with food and water.
Roaches are a great substitute for crickets, for sure, because they are much meatier and gutload super well (and I think they are much less dirty).
But I wouldn't make up the diet entirely out of worms, especially when that includes waxworms as part of the triad. Silkworms, hornworms, butterworms, superworms, etc. are fine but as parts in a bigger diet. So you can eliminate crickets if you want (at least most of the time) but you need to provide other things as well, whether that's roaches, stick insects, preying mantises, etc. Something lower in fat and higher in shell (chams need fiber and roughage too!)
