I'd agree, at least I want them to have their own building chains.You are probably right about the problems with the vanilla nomads and thus I understand that you want to remove it but could you at least try to make them feel a little bit more different from tribals than the pad notes suggest? Maybe make them rely even more on retinues which in turn are cheaper or something like that? Some kind of system with event troops could also work as a replacement for the "manpower" mechanic.
