I did this a year and a half ago, but with an even more niche layout called Norman. https://normanlayout.info/ https://normanlayout.info/ Its goal is to change as little as possible from QWERTY while getting as big a benefit as possible. In particular I like how it preserves the locations of many common keyboard shortcuts that are on lesser-used keys. It also retains the same finger for most QWERTY keys, whereas Colemak changes more in ways that don't feel really necessary to me. It took me roughly 3 weeks to get back to feeling consistently productive, though it was only the first week that was truly frustrating. I don't think I'm a faster typer, but I am a lot more comfortable. I also took the opportunity to switch to an ortholinear keyboard, which has been great.
