Create a worktree for a project using submodules

I have a top project, with about 10 submodules, and some nested submodules.

./top-project/
./top-project/module-a
./top-project/module-b
...

Some submodules have a classic url, like url = git:software/module-a, other have an url relative remote top-project like url = ../module-b. top-project url is url = git:software/top-project.

I want to create a worktree copy of top-project, AND all its submodules.

git worktree add -f ../top-project-v2

But I can't find a way making the submodules pointing to their original path. I would like that top-project-v2/module-a git pointing to top-project/module-a, and not cloning a brand new module-a.

If I do cd top-project-v2; git submodule upate --init --recursive, the command succeeds but submodules are not linked to top-project submodules.

If I do git checkout --recurse-submodules origin/v2, I get an error:

git checkout --recurse-submodules origin/v2
fatal: not a git repository: ../../top-project/.git/worktrees/top-project-v2/modules/module-a
fatal: could not reset submodule index

Is there any way to do so?

If the submodules are not optional or cheap enough to fetch anyway, carry the submodule histories in the main repo as branches and git submodule init; git worktree add for them.
