Yes.

The blocker is config file being shared (you do not want to share
core.worktree and submodule.*). I made some progress last weekend,
just needed to add some tests to see if submodule works as expected
and will post the series soon. Then you can take over if you want ;)

Note that I only try to make submodules work with multi worktree, not
work optimally. A more ambitious goal is sharing submodule repos, so
you can keep disk usage down...
