That would be neat, yes.  Making it work reliably might be difficult,
but a first shot might not be that hard.
Some of the problems:
- the code chunk might be difficult to analyze correctly without its
  context (e.g. the code chunk may start in the middle of
  a comment/string/...).
- for people using the default font-lock settings, it might be difficult
  to find a set of background colors to use for added/removed/changed
  that doesn't make some of the text hard to read.  For people using
  font-lock settings like mine (i.e. mostly all black-on-white, where
  most faces changes the bold/italics rather than the color) OTOH it
  would work fine.  Note that smerge-mode already works similarly, so
  it's not a new problem.
