cp: cannot create link `.git/objects/00/78aeb85737197a84af1eeb0353dbef74427901': File exists

By that time, the object files in the reference tree appear to have
a newer timestamp than the corresponding ones in my local tree, and
cp -lua fails.

I'm now away ,unfortunately, and no immediate idea stems to my mind on
how to fix it. Ideas welcomed - I need to hardlink missing entries from
one tree to another; it would be enough to be able to just tell cp to
ignore already present files.

Could you please try to give cp the -f flag?

Why not just use "rsync" for both remote and local synchronization, and
provide a "relink" command to scan two .git/objects/ repositories and
hardlink matching files together?

With the SHA1 hash, you can even have a --unsafe option that just
compares the has names and does a link based purely off of that and the
stat(2) results of both files.  (I'd expect that a ... safer variant
would extract both files and compare them, but the --unsafe should be
sufficient, in practice, I would think.)
