That does not seem quite comprehensible to me.
Note there have been placename imports using the semicolon variant
extensively, like from NGA GNS, see:
http://taginfo.openstreetmap.org/tags/?key=source&value=NGA%20GNS#combinations
many of the alt_name/alt_name:en there are semicolon separated lists.
Nominatim does not seem to have a problem with those.
From the viewpoint of a data interpreter the semicolon lists are usually
much easier to process than an unlimited number of separate name tags.
Likewise for editing.
Given that neither alt_name_x nor alt_name:x are documented in the wiki,
both variants are hardly used anywhere except western Africa and the
semicolon list variant is actually used frequently elsewhere i would
strongly suggest if you want to do a mechanical edit you change those
to a semicolon list.
