Bad idea.

Yes.  Check out lisp/reveal.el (aka reveal-mode) which detects
(from post-command-hook) when point is inside an invisible area
and makes that area visible (temporarily).

It works particularly nicely with outline-minor-mode (which has special
support for it), but it also work with hideif.el, hs-minor-mode, ...
