Hi Alessandro, Usernames are unique across Wikimedia projects now; so, it is possible to simply union/intersect the usernames from any projects to understand the overlap. There are, however, as you have seen a huge number of users although most are not active in any given month. One approach I have used [1] is to monitor the recent changes feeds for multiple projects for a time period and look at overlap within this data, but that obviously does not speak to longer trends. For that, I would first define a suitable metric (e.g., one or more edits per month [2] or 5 or more edits [3], etc.) to get a list of active editors per project.
