Is the proof of existence of Reinhardt (and higher) cardinals violating Choice dependent on Extensionality in an essential manner?
What I mean is if we work in $\sf ZFA$ would it be possible to have a model that satisfy existence of Reinhardt cardinals and yet satisfy choice?
I ask this question because I saw that $\sf NF$ for example is incompatible with choice but just weakening Extensionality as to allow existence of Ur-elements resulted in compatibility with choice. So can a similar situation be raised here?
