One way to go would be to decrete that keysyms between 0xD800 and 0xE000
(unused anyway) are "KT_LETTER" versions of the unicode 0x0000 - 0x0800.
That however covers only part of Unicode and doesn't solve the case of
keyboards where the upper case of a letter is not simply at the shifted

The real correct solution is really to have kbd use modifiers just like
console-setup and provide a way for them to configure which leds should
be lit when some modifier is locked. That way building a keymap becomes
just orthogonal, no need to upload a table of lower/upper pairs (which
depend on the locale see for instance i/I vs i/İ).
