It sounds like a quite sensible request to me.

Offhand, I do not think of anything that would make it fundamentally impossible to allow us to first add objects to the .git/objects directory by whatever means available to you (including, but not limited to, exploding the object data from a full bundle) and then to tell Git to see if there (still) are missing commits and objects that ought to exist but don't that necessitates the repository to be marked "shallow", and adjust the boundary.

I however do not think there is such a code already written X-<.
