I could test it, but I'm quite sure 4 lines would not be sufficient,
because lazy-highlight relies on much more isearch variables.

Agreed.

Please clarify when it can be changed on the fly.

I don't know how important is to avoid flickering at the beginning,
when it flickers after every replacement anyway.

I agreed on 1.5 points :-)

I very much doubt in usefulness of such a feature. I thought it could
simply highlight the replacement text to show the places in the buffer
that already contain such replacement text.
