I don't know the details of wgrep and occur-edit-mode,
but I guess that after adding an option to specify the
format of the xref output buffer (instead of the hard-coded
xref--insert-xrefs), choosing an option to use a grep-like
output format will allow wgrep to edit it, and choosing an option
to use an occur-like output format will allow occur-edit-mode
to edit it.
