I don't want people to get the impression that this was a "safe" or "smart" thing to do at all. It was a retarded idea but drastic measures were required to get me where I needed to go with diode calibration.

I'm not clear on how you are going to isolate the diode pins from the socket pHaestus. Cut them down so they don't reach?
Speaking from a lot of experience, I'd say using the solder wick on the MOBO is likely to be more challenging for most, than your technique. It's not necessarily easy to get enough of the solder 'wicked' out of the hole to have a clear separation between pin and hole. And, even when you do have a clean separation, unless you fill the gap between hole and pin, there is a risk of the pin making contact with the sides of the hole. (Pressure on the wire when you mount the motherboard.)
It looks like you used 24 gauge wire out of a Cat 5 cable. You could make it much easier on yourself with 30 gauge 'wire wrap' wire. I don't know if you can still get such at Radio Schlock, but any real electronics store would likely have it. (I'll send you 5 feet of it along with 36, 40 and 44 gauge magnet wire if you think you might want to try this on a different CPU.)
I think you are overestimating the risk of damage due to heating from the soldering iron. There is going to be a lot of copper to spread the heat between the pins and the die itself.
The difficulty in doing this is largely a matter of perspective. There are a couple ladies sitting less than 50 yards from me who wouldn't even bat an eye if I asked them to do either of these techniques. (Other than to give me a look of, "Oh, you screwed up and now we have to suffer the consequences." The answer to that is to come bearing chocolate chip cookies.)
