Perhaps someone could try making Reylo work a little better by having Ben NOT be Han & Leias kid ? Make Rey & Ben both former students of Lukes that Luke thought died & he would have no idea they are alive since he immediately cut himself off from the force. Make them both connected more by giving them similar back stories & make them both orphans. To explain the Leia & Rey hug in TFA have it so that Leia & Han could not have had kids & this is why they divorced. Leia during her visits with Luke got attached to Rey as a kid & Han while he visited Luke got along with Ben & they were both helping Luke with rough around the edges students. Luke would obviously let his students still stay in touch & visit family etc
