Has anyone made such a mod? Is it even possible?
No, and to a point…
There exists no way, currently, to read the mod directory nor is there any accessible references in-memory to discern what mods are currently active, however…
As ARK defaults to reading the .ini file if the Mod ID’s are not specified in the launch parameters, it could be possible to discern the Mods active on the server by reading the string ActiveMods from the .ini file by the server, then parsing the string into an array delimited by"," which would return an array of strings with each entry being a mod ID - if any were found, however(again)…
That’s as far as you can currently get. We cannot read the .mod files, which contain the mod name and a pointer to the mod’ PGD… so a database of some form would be required to pull information from - either via the web(usable only by widgets currently - something that sorely needs to change) - or locally(internally) from the mod to display said active mods, but that would require a pre-built database of said information but that is just untenable with almost 2,000 mods on the workshop.
Though, none of that will work if the server is using the launch parameters for selecting active Mods.

Ok. i would use such a mod to see if my own mod was running.
