What I mean is that if you want to mess around with packets below ip level, the other end - your ISP/teleco , will need to be running software that knows what you are doing so that it can reconstruct the packets before routing. If you have a specific need for your upstream not to be delayed more than X ms you could adjust your MTUs/MSS clamp - the size will depend on your bitrate and max delay required.
