Random idea: you could use a script that just replays the merges
present in history and lets rerere record them.  Like so:

-- 8< --
#!/bin/sh

. "$(git --exec-path)/git-sh-setup"

require_work_tree
git update-index --refresh || die "can't run with dirty index"

git rev-list --parents "$@" |
grep '.* .* .*' |
while read merge firstparent otherparents
do
	git checkout $firstparent >/dev/null 2>/dev/null
	git merge $otherparents >/dev/null
	if test -z "$(git ls-files -u)"; then
		echo -n 'no conflicts: '
		git --no-pager log -1 --pretty=oneline --abbrev-commit $merge
		continue
	fi
	git rerere
	git ls-files -t | grep ^M | cut -c 3- | xargs git checkout $merge --
	git rerere
	git reset --hard >/dev/null 2>/dev/null
	echo -n 'recorded:     '
	git --no-pager log -1 --pretty=oneline --abbrev-commit $merge
done
-- >8 --

The intended usage is like

  ./rerereimport.sh v1.6.0..origin/next

to import all resolutions in the specified range.  Granted, it's
probably not as good and definitely not as fast as an automatic
feature integrated with the merge machinery.
