The central assumption that Bell makes is that of locality, or
separability. He shows that any local (separable) theory must give
correlations that satisfy the inequalities. Whereas QM, and experiment,
show that these inequalities are violated.

That is not a valid conclusion. Any local account of the correlations can
always be cast as a hidden variable theory -- if for no other reason than
if there is a local mechanism at play, this mechanism is not evident in the
standard theory (therefore hidden). Everettian many worlds, if they could
actually play this role, would be counted as hidden variables for Bell's
analysis. Bell does not specify what form these hidden variables should

Then give it!
