Geez Doc, you have invested heavily in many parts that have mostly turned out duds. Hope your luck changes for the better soon.
Quite often the simplest upgrades or modifications end up working out best. For those buzzing frets have you looked at raising bridge level a small amount on that side. Sure it will compromise the action a poofteenth but if it gets rid of the buzz, job done. How is the string length and overall intonation as they may be contributing factors too. Whilst on strings what gauge are you running as sometimes really light gauge doesn't have much tension and can also be part of the fret buzz problem.
If it was my guitar I would look at string height at the nut and if ok gradually raise at bridge until buzzing disappears. If neck bow is too concave see if there is enough adjustment left to straighten it out a bit and after every change re-check the intonation. Eventually you will get rid of the buzz and hopefully still have an action that is playable. If not, finish off best you can and hang on the wall as a conversation furniture piece.

I actually tried raising the bridge on the SG till the buzzing went but found that the 12th fret action was too high, I was using 46-10 gauge strings to string both the SG and the LP studio, I also adjusted the SG's neck relief to Gibson factory specs too in the end I found that the sitar-buzzing was caused by the original nut and bridge, the fret-buzzing was caused by some frets that hadn't properly seated near the edge of the fretboard binding, the 1st-fret string height was fine and wasn't causing any buzzing, I'm starting to suspect that when the neck for the SG was made it was made slightly lop-sided, also the nut shelf hadn't been cut exactly 90 degrees to the neck centreline when the neck was made, the only bits of hardware that didn't turn out to be duds were the Nashville TOM bridge and the Entwistle HV58 pickups, they were fine.
Wokka suggested ordering a PBG Bone nut for the SG which I'll do later on, I'm just taking a break from working on the SG and LP Studio that's all, will definitely be coming back to them later on.
Meanwhile I'm going to sort out getting my first ever PBG kit ordered next week.
