I think it’s doable. I recently peeled off one side because mine started showing bubbles and that worked. It wasn’t super easy and took some time, especially to get the remaining glue off.
You can see some pictures here:
I started peeling it off from a corner (had the bed heated) that seemed to make it go easier. I used a scalpel to cut the glue loose at first, but that did scratch the surface somewhat. So better be careful to nut cut into the plate while doing that.
After that I took it outside and used a lot of sticker remover and a glass scraper to get all the glue residue off. It might also work if you start peeling it off to get some sticker remover in between to soak it off.
So is it possible, yes. It did take me 1h30 to 2h to get one side off completely and cleaned. Once you start with the sticker remover, make sure you can do that outside or at least near an open window and that you have a flat surface to work on. (and that won’t get damaged by the sticker remover)
