It would be a good project, but not as 'micro' I would assume. ;)
Why it is not a micro project:

To fix this issue we'd want to fix the .git link files recursively, i.e.
nested submodules would also need fixing. And to recurse into
submodules we normally spawn a child process.

So maybe the plan is as follow:
1) Add the functionality to builtin/submodule--helper.c
    it fixes just one submodule, given by name.
2) add an externally visible command in the same file
  See e.g. module_name (the function and the table
  at the very end of the file)
  (1) needs to call this command (see clone_submodule() in
    that file how to call further commands)

2) "git init --separate-git-dir ../test" would call the function
  in (1), which then recursively uses (2) to call (1) in nested
  submodules.

After thinking about it, it may be good for a micro project,
as it is smaller than originally assumed.
Specifically if you plan to look into submodules later on.

Thanks,
