Isn't there the issue that Unicode is supposed to encode writing?  I
only see two secure precedents for the encoding of multimedia emoji:

1) Korean compatibility ideographs which differ only in pronunciation

2) Character-level mark-up by CGJ for collation to distinguish German
umlaut and diaeresis (if they are truly indistinguishable in all
styles) and by CGJ to distinguish strings for the purposes of
collation.  (Soft hyphens are also usable in this rôle.)

Of course, multimedia *glyphs* are permitted.  Of course, it's rather
tricky to print animated glyphs using muggle inks.
