You probably want to contextually overload the low level keyboard
call back handler 'keyboard-press' in order to achieve this.
Similar call back handlers are 'keyboard-focus' and 'mouse-event'
(see kbd-handlers.scm).

Please read the available documentation on Scheme programming
inside TeXmacs; the idea of contextual overloading is explained there.

I would be happy to know if you manage to get the above idea working.
Notice however that keyboard mappings may need to be contextual.
How do you plan to achieve that? Or maybe you do not care.

I recommend using Scheme for this kind of high level interface customizations.

If you like to use Sage, it would also be interesting if someone could
program a basic API for rendering using native TeXmacs markup
(similar to what exists for LaTeX, MathML, etc.).
This might make it much easier to write interesting and better interfaces.
