Can we shave 60% off of wallet sync times by compressing blocks from remote nodes?

I noticed that the Monero chain compresses about 60%, would it be possible to compress blocks before sending them from a remote node to a syncing wallet thus saving a big chunk of bandwidth and time?

Does anyone know if this is already happening during sync, or if not why?

edit: this can be done using ssh tunnels, if you have ssh access to your remote server. The "-C" option enables compression.

ssh -C -NL 18089:localhost:18089 server_username@server_address

Now you can set your wallet to 127.0.0.1:18089 and now your wallet syncing should be faster, enjoy!
