This is commonly referred to as "ping triangulation" and seems to be reinvented every few years. It sounds good in theory but in practice performs poorly unless ran consistently for days, which is why few researchers end up writing it up or publishing POCs for the next person to find. :)

You should take a look at network path convergence for geolocation instead. You can see a demo of the tool I wrote at https://traceroute.guru/tr/209.216.230.240
