You can purchase one ticket and upgrade with a US20 and get a first class award for 40,000 miles and both will sit in first. I checked and it works for 2/12-2/17. The total mileage cost will be 60,000 miles and a little over $400.
I have no comment on whether or not it is a good deal.
G- Upgraded First from Discounted Coach (non-transatlantic)
D- First Class Award
Z- Economy Class Award
