She's been on tour since what 2015? I think it would be wiser to stop, focus on the new era, let the hype this last leg created build up and then tour.
She can make a whole new tour with songs that she's never performed but imo it's really not needed. People went to see her on this tour and most likely will see the next one. I think she should focus on the new era, new image new music and after that create a whole new concept for a whole new tour and go on the road with that.
