Thanks for the comments. I have made a change to remove the name but put the two "local" ones in the loc_name field separated by a semi colon. This does seem to allow to search for either. All largely based on https://wiki.openstreetmap.org/w/index.php?title=Names That said there isn't an example scenario in that where there is no obvious actual name but local one(s). If you have any other suggestions to best tag this please say.
