I hope they bring other SS members to earth for some goofy fun during fillers. Imagine Yachiru and Kenpachi in Karakura. While I love Renji, Ikkaku, Yumichika, Matsumoto, and Hitsugaya, I think we've seen more of them than any other SS members in the last 50 episodes and they're stretching what little material they have with these 5 kind of thin. Maybe more school oriented episodes, like hollows invading Karakura high school, or a cultural fair with Kon playing gigai-Ichigo. And Ichigo's family never gets boring, same with Urahara's store members. I still want to see those two groups team up for some filler fun. As long as it's not another Bounto arc, I'm satisfied.
