Just looking at Urban Arcana, which is somehow 17 years old. That right there, 100%, should be a priority project for WotC, as a D&D campaign sourcebook.
And as a D&D sourcebook, it should be 100% compatible with the existing system. My current thinking is that real world "mundanes" could just be modeled along the lines of the Expert class from Tasha's. From either the class or some new backgrounds, they get general knowledge of the modern world, proficiency in modern land vehicles and computers, etc.
Once they get into the crossover fantasy stuff, they can multiclass into any standard D&D class, or continue to progress as "Moderns" or whatever you want to call that class. Heroes who make the opposite journey --- Faeruninian adventurers stuck in modern NYC, for example --- might instead take a level in Modern as they adjust to the modern tech.
There are already some Unearthed Arcana spells for techno-wizards. Plenty of design room for similar ideas --- urban druids, Internet bards, and probably a number of classes specifically oriented towards the phenomenon of crossovers.
The fluff from Urban Arcana is excellent stuff, and could be used almost as-is, but alternate campaigns from Harry Potter to Percy Jackson to 80s cartoon D&D are all possible.
