Since this looks like an open call, here are mines which can be yours as well.
Over the last couple of years I have been trying to develop the sound of the harmonica from metallic sounding to something deeper with stronger emphasis on the harmonics.
I made basically 3 diatonics and 3 chromatics which supposed to be a staring point for people who look for different sound and feel. Especially the chromatic “Subwoofer” (the enlarged body in yellowish Cherry wood) has the bottom harmonics pronounced well. Well they all sound pretty good, The bigger the better.
Here are some. If you want to see more info check out the full presentation on https://acoustictendencies.com/
Sure do not hesitate to tell me what you think, whatever that is.
