I just added http://www.emacswiki.org/emacs/FlexIsearch to the wiki.
It's something that I've been thinking about for a while, but I didn't
know how to hook into isearch.  I think it's very close to what the OP
wanted.

This looks interesting.  Maybe you can add an additional level of search between word and flex - treat the search string as regexp.  This way I can map C-s to flex search (right now it's mapped to isearch-forward-regexp).

That is:

start searching for input as string, when not found, search for input as regexp, when not found, search for input as flex term
