Probably worth a call. I have often booked my family of four using two companion fares. As the website instructs, I book the adults first and then use the code to link for two kids. But I assume the system will notice a different routing and throw up an error. Curious to see what happens for you.
Used to be I could use my status to pick seats up front for my pair, and then ask my kids be kindly moved nearby. Last time I asked for that I got a finger wag from the CSR so I am not sure if I can repeat that....
