Rear disk for 8.75 with SBP?

I don't think I am inventing anything new, but has anyone made a junkyard swap (or any swap) for a 8.75 rear with sbp to upgrade it to disks?

I just picked up a set of rear disks from a Liberty and will be following the Mopar Action Magazine articles step by step to add disks to my rear end but in the process of studying everything and measuring all the parts out, I think it is completely possible during the milling process to adapt the backing place to correctly position the SBP axles within the brake calipers as intended. After that, the only custom part you would ever need is standard off the shelf Jeep Liberty rotors that need to get the SBP drilled into them.
I work in a machine shop and can take the time to figure all this out but the real question here is, Is there any interest for it or no? If not then I wont waste my time and will just continue with my BBP conversion with no more distractions
If I end up doing this and if there is enough interest I would strongly consider selling modified backing plates and possibly even the re-drilled rotors on a pre-order basis to save you a trip and hassle to find a different machine shop to figure it out.

Please let me know your thoughts/concerns
