3 Champions to work with Xayah and Rakan

Since the release of Xayah and Rakan, I've always wondered if Riot considered making 3 other champions that are created to specifically work with Xayah and Rakan to have a team synergy of 5 Champions, while also being able to work with all other champions if players chose to main one of them. These 3 champions would take the roles of Mid, Top and Jungle. the 5 champions could all have the option to join in on the base recall, they could also have the 3 new champion ults work with each other in specific ways adding extra damage or creating AOE/CC when used together , it'd be pretty cool to see what riot could do with this. I'm not really sure if it has been suggested before but I think it's a cool idea. let me know what you think
