I think you’re better off just learning the Krita hotkeys and such. Otherwise, what are you going to do if you have to use it on a friend’s computer or library something? You’ll be totally lost.

It’s not hard to relearn keyboard shortcuts. I’m speaking as a user of Photoshop for 20 years who switched to GIMP (as an example) a year ago and had to learn all the differences. If you use crutches right at the start you’ll, never learn to walk.
