Then probably a good idea to do what flycheck does because gremlins.

I think you should test it a tiny bit more and then you push it :-)

ruby-mode.el so it at least locally shares some code with ruby-flymake.

Flymake can use both at the same time. Just

   (add-hook 'flymake-diagnostic-functions 'ruby-flymake nil t)
   (add-hook 'flymake-diagnostic-functions 'rubocop-flymake nil t)

The user can remove-hook if he wants to.

If rubocop does everything "ruby -w" does and more, then maybe a single
backend. One that uses a ruby-flymake-use-rubocop-if-available
defcustom, and then checks for (executable-find "rubocop").
