Sorry for not catching this earlier. The cloning itself might work, but I don't think we support partial-clone submodules right now. In particular, anything that operates on submodules in-process like grep (which either adds submodule objects as alternates or calls the object-loading functions using a different struct repo) will not work, because we only support lazy loading on the_repository. So if we want this feature, there is some other work that we will need to do first.
