I've never had my plants show signs of transplant shock doing that. This idea of roots being so sensitive is just old bro-science that's still floating around out there and repeated by those who don't really know.
Got to be 40 years ago I read about chopping a lot of the rootball off once a year to keep a mother plant long-term in the same pot. Pull it out and reduce the rootball by half or more then stuff it back in the same pot with fresh soil. Tried it on a couple plants 20 years ago and they seemed to like it and the plants really perked up and grew fast. It's like when you top a plant and the side branches start growing faster but happening to the roots.
Give it a try sometime with a spare plant but I'm pretty sure you'll like the results. I do all sorts of nasty stuff to plants just to see what happens. My revival skills have improved immensely over the last 20 years out of necessity.
