I think with the current infrastructure you will have to regenerate
uni-name.el such that it includes information both from
UnicodeData.txt and from MUFI.  uni-name.el will then be loaded when
first used.

Alternatively, I think you could use put-char-code-property to modify
the 'name' property of the PUA codepoints you want to use for MUFI.
