I don't think that all user want to have emacs each time they only
want to install git.

I have a few similar patches (on my laptop) about git.
For example I have add an option that add Tk as a dependency without
recompiling git because git only need it as a run-time dependency.
I haven't patched it yet because I don't know if there is a good way
to create that kind of dependencies.

The idea is the following:

args: with args

let git =
  stdenv.mkDerivation {
    ... normal code ...
  };
in
  if Option then
    stdenv.mkDerivation {
       name = git.name;
       buildInputs = [ makeWrapper ];
       buildCommand = ''
         # use makewrapper to wrapper git binaries
         # sym-link other directories
       ''
    }
  else
     git

At the moment the as a bit change but the idea is here.
