You can buy the size 03 version. That’s what I already have actually. With 03, you can brew 30gr of coffee with 450gr of water in one go.
With 02, you can also brew 2 cups, but using release-steep-release method. Open the valve, add 30gr coffee, then 225gr hot water. After water has passed through, close the valve, then add another 225gr water. Steep for 1-2 minutes, then open the valve again.
Aside from that, according to Lance Hedrick, kono and Stagg also fits.

I did eye up the 03, but I don’t think 450g of water will fill what I consider to be two cups.
Good suggestion about steeping and releasing.
