I think you can use clean / smudge filter in gitattributes for that.

Git does deltification _only_ in packfiles. But when you push via SSH git would generate a pack file with commits the other side doesn't have, and those packs are thin packs, so they also have deltas... but the remote side then adds bases to those thin packs making them standalone: you would have to git-gc on remote.
