But of course!

(setq gnus-completing-read-function 'gnus-ido-completing-read)

I have problems with this, largely because nnmairix (for reasons I will
never understand) creates dummy copies of all your groups. So when you
hit 'j' you're suddenly confronted by a sea of nonexistent groups that
get in the way of where you want to go. Someone in this group, I
believe, once provided me with this:

--8<---------------cut here---------------start------------->8---
(defadvice gnus-group-completing-read (before remove-nnmairix-groups activate)
  (unless collection
    (mapatoms
     (lambda (g)
       (unless (string-match "\\(nnml\\|archive\\)" (symbol-name g))
         (push g collection)))
     gnus-active-hashtb)))
--8<---------------cut here---------------end--------------->8---

Unfortunately this also filters out all my nnml+archive groups, even
though it looks like it shouldn't. Probably I could fix it myself
without too much work, but I haven't bothered…

Anyway, hope that helps.
