I agree with Hauke, as well as being quite unlikely that hobbyist will have better ideas and recommendations than groups of public health experts. These specific ideas also have clear potential to cause harm through taking away PPE from those that most need it, and plausibly causing an increase in transmission through touching inside of masks and risk aversion behaviour. Even ideas that would have small expected EV in transmission, have the potential to cause harm overall in expectation as they could diminish trust of future public health pronouncements.
