If I'm not mistaken, isn't this already done by the compose input
method?  The commentary says,

    ;;; Commentary:

    ;; This input method supports the same key sequences as defined by the
    ;; standard X Multi_key: https://en.wikipedia.org/wiki/Compose_key

    ;; You can enable this input method transiently with `C-u C-x \ compose RET'.
    ;; Then typing `C-x \' will enable this input method temporarily, and
    ;; after typing a key sequence it will be disabled.  So typing
    ;; e.g. `C-x \ E =' will insert the Euro sign character, and disable
    ;; this input method automatically afterwards.
