Replacing WordPress Icons (menu,icons32, etc)?

Question

I want to replace wordpress admin sprites. I recreated the images and looked answrs for icon replacement using jquery and simply with CSS BUT what about ones link icons32-2x.png where I can't find the CSS?

So I am trying to figure out a simple way to redirect the wordpress admin and includes folder to use my new icons INDIVIDUALLY.

Again this is just not for custom post type icons but all.

Basically I think through jQuery using replaceWith new icon but how can I replace an image if I don't know where its called in CSS (i.e. retina images) so I need a resolution to direct specific images in admin wp-admin and wp-includes folder.
