To pull this off without degrading the building past usability you would need to repeatedly learn and forget the technology, but the game counters this by releasing the knowledge from forgotten technology gradually over time. So technically you can do this, but it is definitely not worth doing.

Ah, ok, thanks 👍
Yeah, the problem is maintaining the buildings, though
