Alternate keyboard layout support inside modal editing

Is your feature request related to a problem? Please describe.

I've been using (n)vim for a while now and I shifted to colemak keyboard layout a few months back. So in vim, this switch was very easy as there's support for langmap. Would it be possible to have something so that I can use the actual keybindings in modal editing (ex: h, j, k, for navigation, but inside colemak I can just press h, n, e, i instead and it'll do the same). This is so that I don't have to rewire my brain and also have a boat load of binding changes. Thanks!

Describe the solution you'd like

Langmap support from vim would be a nice place to start. Alternatively, if there's first class support for alternate keyboard layouts that's also a really good solution.

Describe alternatives you've considered

I'm not that interested in rebinding all the keymaps for it to work. Let me know if there are alternatives.
