Isn't that a bit counter-productive, like Arefu?
No, since they're built on the cliff they don't have to worry about wildlife as they're out of the way from them.
And there will be lots of bridges crossing between the cliff houses as opposed to Arefu that had one way in.
Besides, it'd make their tribe more unique design-wise as opposed to Great Khans, Arroyo, Primitive Tribe, Punga Tribe and the Zion tribes.
