In a post on his Instagram account, former WWE wrestler Jack Gallagher revealed that WWE had Cruiserweight Tag Team Titles created and ready from the time 205 Live debuted in 2016. The titles were purple and gold and were found on the prop truck which was brought to weekly television. They were never officially introduced either backstage or on television. Rules suggested for the titles included lucha libre rules for tag matches, meaning both feet touching the floor allowed the partner to come in, or trios titles. There is nothing to suggest that these titles will be introduced at any point in the future.
This would have worked well. Check out some cruiserweight teams worthy of the titles:
