Cover Traffic

[2600denver]

I know that the tor wiki suggests that people use cover traffic in order to
increase their anonymity. Since each link is encrypted, why don't servers
create their own cover traffic using a 1:2 rule. For every one packet it
recieves, it sends 2 blank packets. An adversary observing the connection
wouldn't be able to distinguish between cover traffic and real traffic
(perhaps cover traffic could even have a different private key)
Here's how I imagine it working:


you-->(one packet, two covers)tornode1-->(one packet, two new cover
packets)tornode2-->(one packet, two new cover packets)tornode3-->internet

Once the cover packet  is decoded by the next server, it will recognize it
as a cover packet and simply drop it and generate two new cover packets.
Does this seem like a plausable solution to stop timing and point-to-point
attacks?
