Seems doable, does this work for you?

Subject: [PATCH] Let ido-everywhere turn on ido-mode (Bug#34292)

* lisp/ido.el (ido-everywhere): Turn on ido-mode, if it's not already
on.  Otherwise, having ido-everywhere enabled messes all file and
buffer reading interactive commands.

(it seems to be working for me now, though I had a transient failure the
first time where it refused to open bar, even though ido seemed to be
functioning correctly.  Maybe a caching thing?)
