I agree with the above suggestions for how to break them up! I also just looked through the tagsets for Agent Carter, Jessica Jones, and Daredevil, since I'm familiar with all three shows, and I don't see any tags that are out of place or belong better in another fandom (wellll, maybe "James "Bucky" Barnes & Peggy Carter & Steve Rogers" in Agent Carter, since these are mostly MCU characters -- but it could be there as an intentional crossover relationship). Anyway, I think there is not a whole lot of overlap between them in terms of the pairings that people nominated, and they seem to be fairly separate as fandoms too, in my experience.
