So what about the E. Suter Aplanat B No.6? If my memory and guess is anywhere near good, that should be a portrait lens for ULF: No.3 covers 8x10", although Aplanats of that age gives very soft corners. A No. 6 is for "Imperial" platesize, which was something like 40x50cm, or 16x20". Assumins a FL similar to the plate diagonal, that's a 640mm lens with perhaps 40° usable coverage for reasonable sharpness. That's still a 465mm image circle...
No, I don't need another ULF lens. At least not until I have a ULF camera
