subtree might be better for exactly that? I have a project with about 100 repos, developing with them individually is so much saner, but every so often you want the one actual benefit of a monorepo: fast really-global search. So keeping a subtree-of-everything (using the bitbucket api to get the list of repos) and then just doing git-grep there when I want to see any use of something. (Somewhere there's an apt hook for "grab sources for everything that apt installs"; having that extract the source and git commit it, or just get the upstream repo from the metadata and `git subtree add` (or pull) wouldn't take much...)
