I think that raw X11 key events might actually encode key positions (or numbers based on a particular arrangement of keys) but maybe they are not easily available at the layer your key events arrive. But the actual question is a different one: have you considered offering a chromatic button accordion arrangement "on top" of that national remapping? Basically it would mean that a chromatic scale is encoded as zsexdrcftvgybhunjimko,lp.;[/'] for C system (with a qwerty keyboard, starting at C) and qazwsxedcrfvtgbyhnujmik,ol.p;/ for B system (again, starting at C). Finnish G system uses the same scale as C system apart from starting with C♯ rather than C in the first row. I can provide images if necessary (there are some at <https://en.wikipedia.org/wiki/Chromatic_button_accordion>). Modern CBA keyboards tend to have 5 rows but the inner 2 rows are repeats for making transposition and chord fingerings easier and basically every player can get along without them at least when doing note entry. So whether to offer more than 3 rows depends on whether there is an actual use for the numbers and function keys. The main advantage for CBA players of course is easier entry. The main advantage for everyone else would be access to more notes at the same time.
