You can use the core.worktree config variable in order to specify a
worktree (/etc) which is not directly above .git. For your git commands
to find the .git dir you would need to set GIT_DIR or use the --git-dir
parameter.
I have found, though, that several git commands require you to be within
the worktree or else they become confused. I use a shell function for
that, doing something like "gg ~/path/project log" which requires
~/path/project.git to have its core.worktree set. Also, having a git
alias like "git view" set up for gitk helps calling gitk in that way.
git-gui makes unfounded assumptions and is completely unhappy in a
situation like that.
I think the situation around GIT_DIR and and worktree is a bit in the
flux at the moment (panta rhei..) but it works for me.

Here's the "git go" bash function. I'm not proud of it, it makes several
assumptions and does no error checking. Use it like "gg path/project
command parameters" if the git-dir is "path/project.git" or "gg
path/project/" if the git-dir is "path/project/.git". Have your
core.worktree set in the former case, and also in the latter if the
worktree is not "path/project".
I'm sure it can be done much better using helper functions from git's
bash-completion, e.g.
gg ()
{
local _gg="$1";
shift;
local _ggwt=`git --git-dir="${_gg}.git" config --get core.worktree`;
if [ -z "${_ggwt}" ]; then
_ggwt=$(cd ${_gg} 2> /dev/null && pwd -P);
fi;
local _gggd=$(cd ${_gg}.git 2> /dev/null && pwd -P);
pushd ${_ggwt} > /dev/null;
git --git-dir=${_gggd} "$@";
popd > /dev/null
}
