Sure. Implement the key jitter-time-shift idea now. Then later you can add stuff that requires the receiver to understand it's chaff.
Ideally, the packets should be the same size, so keys and chaff should both be the same structure except that the chaff has an extra bit saying it's chaff.
An alternative that may be implementable now (I don't know much about the SSHv2 protocol) is to use a bogus encryption key so that it is rejected on the receiving side. That'll add additional confusion to anyone trying to break the stream as they'll have to separate the differently encrypted packets from one another.
Ciao!
