what do you think of a device to pitch each side of the fifth wheel up and down (pitch in the direction perpendicular to the chasis) so you can manually level the fifth wheel to the trailer at many steep angles, even pick up the trailer, and then manually level the trailer by pitching the fifth wheel, to slide the king pin in on the first try, most of the time?

I believe if the fifth wheel was allowed to tilt side to side on top of front to back the trailer would be pretty unstable. The only thing keeping the trailer upright would be the tandems way at the back of the trailer. The fact that the fifth wheel can't tilt side to side helps stabilize the trailer. If it could tilt side to side and it was loaded heavy on one side it would be in a constant lean. This style fifth wheel you're talking about is used a lot in the camper world. However the wheel bases are shorter and there's a big weight difference and the trailer center of gravity is different.

I do believe that belly dump trailers have this on the kingpin. If it was added to the truck it would add weight, and another wear point. Both of which is not needed. If the trailer is tilted, the truck should tilt some to when backing under. Most have air bags which allow some degree of tilt, when on uneven surface.
Not a bad idea for offroad use, but I can't see why it would be needed for hooking up a trailer. Usually are left parked on level ground.

A standard Off Road fifth wheel does tilt side to side. When working in the woods on uneaven ground you will need that extra axis of motion to keep the drives in contact with the ground. These have a lockout that you need to engage to prevent the side to side roll when going down the road at highway speeds, otherwise a small bump would start a dangerous oscillation resulting in the truck and trailer sliding down the road on one side or the other.
