I wrote about the qali-*-an place names here. Though I think *qalis-an is the origin of present day place names such as Alisan 阿里山, Hemei 和美, Jiali 佳里, and Jialixing 佳里興. Though, ka-lé-san used to refer to all tall mountains in the south, not just limited to Alisan. The people Tsou living in Alisan also refers to where they live as psoseongana instead. kali was just the name given to them by the Pingpu people living in Jiayi. I am not 100% certain if it has relations to the old name given to the Paiwan and the Rukai people, Ka-lé (傀儡).
I wonder if the etymology of Alibang can be found in the Kaxabu language, which would be the closest language to what was spoken there.
