David, I have a B&W hitch. I love it. They have a non-slider that will mount into your bed rails called a Patriot. A friend just bought one and loves it. It is a smaller version rated @ 16K instead of the normal 18/20K

I do not think there any cost effective way to put a B&W head on a Reese.
I would refer back to how many times have you really needed your slider function on your Reese?
Jim
