I'm in the same boat as you! Just started working on proper touch-typing a few weeks ago, as I sometimes found myself being ashamed of my self-taught ~7-finger typing system.

Commenting primarily to see what others have to say about your idea, since I can notice that sometimes when I don't pay full attention I tend to use my "old" mental keymap and cheat a little bit.

Im in exactly the same boat. I was thinking something like this might be so radically different that it breaks my bad habits? https://www.zsa.io/moonlander/ Not cheap but I would pay a lot to be able to forget how to type and start from scratch, properly...

If you consistently push yourself towards touch-typing, there seems to be a slow increase after the first plateau. Depending on your age it'll take more or less time.

Maybe see my other comment I replied to OP, it may provide you some insight.
