why would you do that... use aircon sparingly.. get used to it. At the end of the day youl never adjust living in permanent aircon.. I use it at night and when I first came after a few weeks increased by a degree... then again after a few weeks etc.. I sleep now at 28c...below that I'm honestly freezing!
the key word in the original post... 'theoretically'.
Until it happens don't worry about it.. I've watched several lawyers youtube videos and the seem to think that it's probably not happening as it will be very hard to enforce. Also other news sources think that the rich and powerful Thai people (who this is actually aimed at) won't allow it to happen and use their obvious influence on the government... my personal prediction it will be delayed and then fade away.
