Philippe and others,
You are missing the relevant parts of UTR #51. See:
• http://www.unicode.org/reports/tr51/#Multi_Person_Groupings <http://www.unicode.org/reports/tr51/#Multi_Person_Groupings>
• http://www.unicode.org/reports/tr51/#ZWJ_Sequences <http://www.unicode.org/reports/tr51/#ZWJ_Sequences>
This type of behavior with ZWJ for emoji is already in use.

Compare this to the association of the sun and the rainbow symbols, or the cloud and a rainbow (and compare to the sun or moon and a cloud associated the same way, or the association of two clouds: none of them will overlap completely).

It may just create a small partial overlap of one symbol into the other, but each one is still clearly identifiable separately. The examples shown are for grouping multiple persons in Annex E but each person is still separately visible and recognizable as such even if they are combined in the same final glyph. Annexe E even requires some specific orders (e.g. for families: the man can only come before a woman, and is then necessarily visible to the left side of the icon, i.e. to the right of the woman; children are necessarily after and below adults...).
