Which is why I went on to suggest that the Swedish manuscript ampersand
form (the 'och' abbreviation) might be substituted 'in Swedish text'. The
OpenType glyph substitution model, for example, associates lookups with
particular script and language system combination, so it is possible to to
have something like this:

         Latin <latn>
                 Swedish <SWE>
                         Stylistic Alternates <salt>
                                 ampersand -> ampersand.swe

This substitution would only be applied in Swedish text. Now, this
particular aspect of OpenType is not well supported yet, but it is a viable
mechanism for the kind of substitution that the 'och' glyph requires.

Please note that I am not saying that the 'och' should not be encoded, only
that there may well be good reasons to consider this form as a glyph
variant and existing technologies for dealing with it as such. In order to
make a case for encoding the 'och' ampersand, I think you will need to
demonstate a need to distinguish it from the regular ampersand in plain
text documents.
