I don't think you can realistically.  You'd probably have to hack some
standard library and I would not even consider opening this can of
worms.

Don't we all have from time to time? :-)

You could still use IRB with FileUtils loaded.  That looks like a more
promising approach.  You can't reuse all your shell scripts though.
But for that to work a shell script interpreter in Ruby could help.
But then again: if you softlink /bin/sh to /usr/local/bin/ruby all
your interactive shell functionality is gone (or must be emulated by
Ruby).  And that topic comes up from time to time but I do not think
it's a worthwhile approach to pursue...

Kind regards
