As long as "${repo}/worktrees/${wtid}/gitdir" and
"${worktreepath}/.git" are agreement with one another -- that is,
pointing at one another -- everything should be fine. That's all
that's needed for healthy linkage between the repository and the
worktree. You usually don't have to touch
"${repo}/worktrees/${wtid}/commondir" -- unless you have some really
funky layout -- since that normally just points up at "${repo}".
By the way, you may be interested in the new "--relative-paths" paths
option of git-worktree and the related configuration
"worktree.useRelativePaths" and "extension.relativeWorktrees" which
will be part of Git 2.48.0 release, and which was (at least in part)
motivated by the sort of use-case you describe.
