Yea, I've been thinking about adding fancy features like those.
But been lazy.  Spawning the user's preferred editor would be a
nice way to get some of that.

Probably.  git-gui already has the data from .git/config loaded in
memory, it should be fairly simple.

With my busy schedule its unlikely to happen anytime soon either.
But I've added it to my todo branch.  Sometimes things on that list
get accomplished.  ;-)

An annoying work-around would be to run your editor to create/edit
.git/GITGUI_MSG (or .git/MERGE_MSG) then hit Rescan in git-gui.
It loads that file into its editor buffer if the editor buffer is
empty or has not been modified from within git-gui since the last
time the file was read.
