B&W Companion with Hidden-Hitch Hide-a-Goose?

IIRC the Companion has a square receiver while other goosenecks tend to have a round receiver. The Companion has a square shank that goes into the square receiver which gets latched in by the handle in the wheel-well of the truck.

I haven’t seen a shank for Hide-a-goose that would work with the Companion.

Now, the Andersen Ultimate Fifth Wheel hitch would work great with your current hitch and use the ball that Your hitch uses.

Thanks!
