1. What's wrong with keeping C-s and C-r for searching minibuffer text?
That's useful.

2. We have M-s and M-r for searching the history.

3. I proposed M-o for completion against the history:

(That link also describes other useful ways to access history items.)

Pick a different key from M-o, if you like, but a separate binding for
history completion is better than co-opting the isearch bindings.
