This seems currently not possible with the standard way to pass down the prefix.

The problem is, prefix is meant for inside worktree area only. Many
code paths are not ready for prefix "../". Worse, in some cases when
you launch outside worktree, prefix is empty and I think some builtin
commands rely on that. However, I think you can introduce "prefix v2"
that is used in parallel with "prefix v1".
