There is no way to reconcile those histories.
I do think this is an interesting point: the current Wikipedia policy of allowing each language's Wikipedia to evolve independently risks missing an opportunity to free certain non-English speakers from some of the unfairness that results from happening to have not been born an English speaker.
(With no disrespect to the Wikipedias of other major languages, I'm sure they have many extremely high quality articles. But I assume that in, say Math, Physics, Computer Science, the English Wikipedia is the highest quality.)
Why would you think that English content in mathematics is the highest quality in comparison to other languages? Your thinking is flawed.
In my experience, non-English Wikipedia articles are great for "insider knowledge" about topics and/or local figures who are deemed not relevant enough to the English Wikipedia editors. But outside these niches, their texts tend to be both shorter and less polished.
Source?
EDIT: Or do you mean contain the same information between different languages of a specific article?
Such as, for Carnival, being written in a language spoken by a people who celebrate it, or for Alexander the Great, highlighting the languages spoken in territories he conquered.
It's an interesting proposal, but I get a headache just thinking about the politics of implementing it.
It is possible to link images and other things via Wikimedia, and my understanding is that Wikipedia does push for people to do this.
