In one of my packages, I use a loop with completing-read to query the user for a list of words. Inside the prompt, I'd like to bind DEL to a different command.

How can I achieve that?

The solution also needs to work with ido-completing-read (possibly with small modifications of course).

There are of course keymaps you can bind stuff to. For example you could temporarily merge minibuffer-local-filename-completion-map with your extra keys. From the documentation:

Local keymap for minibuffer input with completion for filenames.
Gets combined either with `minibuffer-local-completion-map' or
with `minibuffer-local-must-match-map'.
  • Will this keymap be applied even if my prompts have nothing to do with filenames? – Malabarba Jan 8 '15 at 17:05

Just have your command bind the key you want in the appropriate minibuffer keymap, and then unbind it there when the command is done.

[You do not need to merge keymaps. You just need to bind the key in a map that is already being used (whether it was merged or not).]

The minibuffer keymaps that involve completion (depending on your Emacs version):

minibuffer-local-completion-map  
minibuffer-local-filename-completion-map
minibuffer-local-filename-must-match-map        
minibuffer-local-must-match-filename-map
minibuffer-local-must-match-map
