I've written something similar in the past and it wasn't met very well by a few members. Someone even told me that I was dreaming, while I've explained that with the Lightning Network development this will be a reality.
I understand that the narrative currently is to pass Bitcoin as a hedge to inflation and perhaps a way to cure all financial disease and fix everything. This is not true and everyone knows this. Bitcoin has two purposes which are interconnected. It is both to be used as a method of purchases and has also features of a store of value asset. It can't abandon any of these as it will fail in the other too.
I think it'll be technically possible but users simply won't want to do it en masse. You don't spend what you think will be worth more in future, especially if you have a more common alternative that does the opposite. It goes against human nature and hardly anyone resists that.
