I thought I'd try it, just to see, and it turns out that C4D won't let you render single pixel high images. The smallest you can do is 16, so that dog don't hunt. (Oh, in some ways I still miss you, Electric Image!) Octane Studio lets you go down to 4, which may be enough for the effect, especially if you add and overlay a pixel interpolated strip between each rendered strip in the assembled composite, giving a decent approximation of 2 pixels per progressive scan line.
My test render was wicked fast on a single 4090, rendering a moderately complex scene, 1920x4 pixel strips x 270 strips per frame, and rendered 1000 strips/4 frames in about a minute. I didn't set up the camera to do a proper vertical scan, though, just a simple orbit; I just wanted a feel for how long it would take. Maybe tonight I'll try the real deal.
It looks like this is a more practical option than I had expected it to be.
