Fuji C600 can cover 20x24 wide open. 600mm is "standard focal length" for 1620
Because I like old glass, I'm thinking landscape meniscus. A large ROC, Waterbury, or others are fairly common. Also, you could get about a 14" convertable petzval (someone has to do the math, I'm just guestimating) such as a Wollensak Vesta, remove the front achromat, put it on the rear, and stop it down. That's a cheaper way to get a long, fairly wide lens that can be very sharp stopped down. Or the Gray Extreme Wide Angle, Protar VII, Wollensak EWA can be found somewhat cheaply. Even a 14" Dagor might cover stopped down.
I'm not giving you the exact focal lengths of the above to use. You'll have to do your own research. But these are tried and true wide angle solutions for landscapes.

The 760mm Apo-Nikkor will cover 16x20 format and there are a couple on ebay right now.

Thanks for the replies everyone, this will be truly helpful when I know I can do the other part of the equation in terms of image presentation. This is probably about two years out to be honest.
The Fuji 600 is frequently used on even 20x24, with what limitations I cannot say. Otherwise I'd look at a process Nikkor in the 600 to 760 range or beyond, which should have an ample image circle. That would at least give you a "normal" perspective.
Yes, the 610 Apo-Nikkor will easily cover 16x20 and allow for generous movements. Nikon lists the image diagonal at 1,030mm or 40-1/2". You can still find this lens for vey good prices - I bought mine new in its box for $500 - and they can be mounted in an Ilex #5 shutter. According to Nikon, the 420, 455 and 480mm Apo-Nikkors will also cover that format: The image diagonal of the 420mm is 710mm or 28".

Buy a lens when one comes up -- and then get a camera to match it!
