Roto Flex will set you back around $700 and the B&W hitch another $1200.

You are correct that changing over will be expensive. ANDERSEN Rota-Flex Lockout Kit (3247)If you plan to use an Andersen Ultimate Connection with a Trailer Rota-Flex Pin Box, we recommend that you install a. Another part of that solution is the Curt Roto-Flex pin box which also absorbs a lot of the motion. BTW, chucking was always a problem with my gooseneck horse trailers. I don't know if the same will be true for the gooseneck. See the attached picture that's my "avatar". I have it set at the upper position and the clearance to the box is more than 6 inches and the trailer sits level. It also keeps the rubber pad in your Rota-Flex pin box from shifting over time. This hitch is great for off camber hitching. Manufacturer Part : 3247 Thoroughbred Diesel Part : ANH3247 Fitment Notes: Universal Our Rota-Flex Lockout Kit is required when using an Ultimate 5th Wheel Connection with any Rota-Flex pin box to prevent damage to the hitch and/or tow vehicle. The B&W Companion is very quiet and there is absolutely no chucking. I'm sure there are fifth wheel hitches that suffer from "chucking" and noise. In fact, because the hitch breaks down in two pieces, I can take the whole thing in/out by myself. Very secure and not a permanent mounting. My truck has the factory gooseneck/fifth wheel package which allowed for a drop in B&W hitch using cam locks. I won't say that is unsafe, but would say "suboptimal". My estimate is that situation puts an upward strain on the ball any time the front of the trailer goes down. The offset you have creates a lever where the pin weight is behind the ball. The gooseneck adapter changes that to a point load. If you look at a gooseneck horse trailer there is considerable "webbing" along the hitch to distribute the load.

The gooseneck adapter changes the geometry of how the load is distributed quite dramatically. Fifth wheel trailers are designed to carry the hitch load through a pin box. The gooseneck is not more solid the fifth wheel hitch "captures" the pin more securely and allows significant articulation both side to side and front to back. Again, these are my opinions and others may disagree.
