there is a parsefunc which modifies the content of a field (for 
tt_content it is 'bodytext'). but that function does not interfere with 
any images (AFAIK). its just: wrapping 'lines' with <p 
class="bodytext">|</p> and solve those TYPO3 special link tags <link url 
target ...>|</link>.

you may hook any userfunc or additional computation to the rendering at 
all, but there is nothing you can do with just a little configuration. 
and especially there are no hints to the original image, which you need 
to have images in bigger sizes than the inserted.

I think as the concept of responsive websites and the usage of images in 
multiple sizes needs a complete different approach not much converting 
is done but a new relaunch which uses the new features.
As I llok at websites which have been doen more than five years ago: 
images were optimized for the usual usage and that was a maximum of 
800x600 pixels. so there would be no possibility to enlarge images to 
fit a something like retina displays.
either you need to replace a lot of images, or you stay with the small 
images for older pages/data and only the new data gets images with 
multiple solutions.
both times the editors have to change their workflow / use other CEs
