Maybe I misunderstand by why is this considered impossible? Network processors read data from a packet, make decisions based on that, and then rewrite arbitrary parts of the packet. All on the fast path. This sounds doable if you had the custom firmware that did that. It'd just be a huge waste of money considering your very, very expensive network box.
