Hi @apapyn,
Have you had a chance to look at https://pkp.sfu.ca/bugzilla/show_bug.cgi?id=5598? This is a rather old PR that got partially completed in order to implement multilingual author names in the same style as other multilingual fields; its approach is consistent with the rest of OJS’s multilingual structures, if you’re curious how those work.
There are also some general web system recommendations that might be worth considering against your requirements here:
