I was not thinking about simplification, but rather improvement.

Well, that is one of the things done in preview-latex. Do you have
the bounding box information for your images (preview-latex takes them
from TeX usually)?

preview-latex provides a working view of the buffer straight away,
rendering images and replacing place-holders first on the displayed
screen area, then off-screen. That way, you get immediate visual
feedback where you need it, even though the rendering of thousands of
images might take a minute or so.
It is really several years of optimizations and user feedback that
went into the code base. You should take it for a test drive before
deciding that its behavior does not suggest interesting material to
your project.
