Bed Roll Bar + Full Size Tire Mount?

I know I haven't seen this exact product out there, so maybe I'm just looking for guidance on it, or estimates from someone in-the-know for what abouts it might run me to get one fabbed up.

I want a non-structural roll bar that I can mount aux lights to, but which doesn't interfere with the brake light. Ideally tack on some handles, two on the slanted support beams and two on the horizontal-ish members. I'd also really like to have detachable beams that dip down into the middle of the bed, on which I could mount a full-size spare (but then take off for bed space). Don't want a product that's got the crossmember between the vertical and slanted beams on the sides, and would ideally like the shape of it to roughly match that of the cab.

So how deep do I need to dig into my pockets to make something like this happen, or have I just somehow missed a product that mostly meets what I'm looking for, maybe?
