I searched for similar issues and have not found anything, hopefully I have not missed anything this time.

Note: I am not 100% sure is there some licensing complication, I admit that I have not researched this aspect situation strongly enough to be sure.

This is not going to happen at least not on the official instance. Nominatim is explicitly there for searching in OSM data. Adding Wikipedia names would just cause confusion.

We do need to do something in terms of translated category terms, see my thoughts on that in #2944. However, I don't think that any solution there will ever cover this particular case because 'mound' wouldn't really be covered by natural=peak (among other things, there is nothing natural about it). historic=monument would need a subtag that describes the 'mound type'. But this is a tagging discussion that does not belong here.
