That is all fine and good if you kill a data-lane. All of the power provided by PCI-E is provided in the first 11 pins (either side) of a PCI-E slot. Everything after the PCI-E key is only PCI-E data, clocks, and grounds. I also don't think that PCI-E is as resilient as you are describing. If you fry a lane there is a good bet there is more damage to the PCI-E controller as well. PCI-E also uses 12v and 3.3v.
