Is Helium a quick fix for Helmholtz resonance?

Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!

Is Helium a quick fix for Helmholtz resonance?

I see some people here who seem to struggle a lot with Helmholtz resonance, and I have been thinking some about this problem on and off for a while. Some time ago it struck me that the resonance frequency of the cavity would be significantly raised if one could add some helium to the air! The reed frequency should not be too affected by this, but as I mostly play low tuned harmonicas I haven't gone about trying this myself.

This might not be practical for gigs, but it might be fun to try! If anyone does, let me know about the results :)
