But then we lack the numeric order. For example for the numbers 1-24,
30, 40, 50, 60, 70, 80, 90, 100 the collating sequence of the Latin
letters give:
C, I, II, III, IV, IX, L, LX, LXX, LXXX, M, V, VI, VII, VIII, X, XC, XI,
XII, XIII, XIV, XIX, XL, XV, XVI, XVII, XVIII, XX, XXI, XXII, XXIII,
XXIV, XXX
and then for the kings of France, "Louis IX" (Saint Louis) precede
"Louis V" and an hypothetic "Louis XIX" would have preceded "Louis XIV"!
I understand the restriction of use for compatibility, but I think that
we really lack at least, the following figures necessaries to write
every roman numeral:
I, II, II, III, IV, V, VI, VII, VIII, IX, X, XL, L, XC, C, CM, M
encoded each as a unique character in a continuous sequence, with
corresponding numeric properties.

Note that the Italians already in the 14ht century built tower clocks with Roman numerals from I through XXIIII (with XVIII at the top, because they began the day at sunset).
