I’d like to copy my keymap and phrases from one instrument to another, can this be done without exporting every phrase separately, reimporting and re-making the keymap?
Sounds like you might enjoy giving PhraseMate a spin?It recently got batch import & export of phrase banks.

It does not recreate the keymap 1:1, but you can still control how (and if) keymappings are created.
