If we had a BB18 style “returnee” season

Who would you most want to come back this year, if it were only 3-4 returnees and the rest of the houseguests were newbies? People always ask about the next All Stars cast, but it’s much more likely imo that we get a small amount of returnees like season 13, 14, 18, etc. We could also get a single returnee like seasons 11 and 19. Would do you think would be the most likely for them to bring back? And who would you personally want to see come back?
