A seemingly straightforward solution to the “unambiguous mapping”

unequivocally denote the current Swiss flag. No need for separate lead
and trail. Simple.

Doug,
you put your finger on it. Any form of combining scheme is doomed to fail.
This includes the current approach of "Regional indicators".
The simple reason is that the use case is too remote to attract
implementer attention, and, because the users community is not, in
principle, limited, implementation support would have to be widespread
to make any of these schemes work if&where desired.
The lesson for the UTC (and WG2) should be to cease such efforts of
"meta encoding".
