using icicle to complete evil ex arguments?

Hello,

Is it possible to use icicle to complete evil ex arguments? Concretely,
assuming you have evil installed, if you type (to switch buffer)

:b<space><tab>

you get the usual completion list from emacs. Could it be possible to
use icicle to complete this buffer argument?

I took a quick look at the code, and currently <tab> in the minibuffer
is bound to this function:

#+begin_src emacs-lisp
(defun evil-ex-completion ()
  "Completes the current ex command or argument."
  (interactive)
  (let (after-change-functions)
    (evil-ex-update)
    (completion-at-point)
    (remove-text-properties (minibuffer-prompt-end) (point-max) '(face nil evil))))
#end_src

If I understand the `evil-ex-update' function, it parses the current
command line in the minibuffer to set up things such that completion at
point knows what kind of completion to do.

I don't really know where to go from here …

Thanks,

Alan
