not. However, if you insist that you can find somewhere with git fsck or if you really desperately need bandwidth: rsync
rsync -hxPavilyzH --delete user@remote :/repo/origin/.git/ brokenclone/.git/
To find out what acceleration / throughput optimizations you can expect:
rsync -hxPavilyzH --delete user@remote :/repo/origin/.git/ brokenclone/.git/ -n --stats
