But the first step to making this feasible will be to understand which properties in Wikidata should be updated in which ways.
For now it seems the most common approach is to provide a direct link to the existing statements, next to where they are used by the template. https://commons.wikimedia.org/wiki/File:Wikidata_Russian_Wikipedia_statement... A template also has knowledge of what properties it's looking for, so it can produce a link as placeholder where the statement is missing as well.
