You or, anyone here can pretty much do that right now. Except for signatures...

Go to customize, scroll down until you see "If you are on a slow connection, choose the Standard Graphics mode to decrease download times.", select "Standard", then click "Customize!", and boom images in posts are no longer displayed. It still shows signatures but, Avatars are gone and, images in a post are replaced with the img tags and, the url.

So, aside from signatures it's an option already there.
