Banchan Lama is another head of Gelugpa sect, so the religious landscape for the small religious population isn't going to change. But it doesn't matter really because of following.Or just get rid of him because probrably the other tibetan schools (Nyingma, Sakya and Kagyu) will take over and replace the Gelugpa.
I do agree to PRC terminating the Dalai lineage by not selecting a new Dalai lama. Unlike what western media says, I don't believe Chinese Tibetans care much about such religious figure head, most young tibetans with proper education are likely atheists. It took a short time, two or three generations for Europeans to throw away the church, for Han Chinese to throw away emperors, why should Tibetans be any different. It is only in western propaganda that somehow Tibetans is a different human species who are genetically coded to be more religious.
