Possible to replace WebKit with another rendering engine?

Webkit is at the core of not only Safari but all services that rely on it, these are iTunes Store, the Wikipedia articles built into Dictionary application. I wonder is it possible to replace it with Gecko or Chromium for better compatibility and how demanding and laborious that task would be?

You mean replace the rendering engine in Safari and the OS?

No, can’t be done in any practical sense.
