As I said, you can already do that with the triggers on both oculus and vive controllers. Unlike the other overrides, they are not simply "on-off", they have analog input values for the shapekey value based on the amount of pressure you apply to the trigger. I use my vive triggers to control my eyelids so I can manually close my eyes very slowly and give people the bed eyes look, or smile and look really really smug.

In the past I've already done what you're describing on my lewd models. Triggers to control vaginal dilation. Index and WMR controllers can't do it, only oculus and vive controllers can, afaik.
