Isearch doesn't add regexps to the regexp history for the good reason,
and I don't propose to do this anyway.  What I propose is to add the
last isearch string to the list of default values available in the
minibuffer by typing M-n (not history values available by M-p).
And Lennart proposed also to put the last isearch string to the
minibuffer's initial input if the last command was isearch-other-control-char.
