Hey dude, I know exactly where you're coming from, I have a HSS Yamaha Pacifica loaded with a Nailbomb and 2 Trilogies, and I used to be totally fed up with neck single coils, especially for lead work.
With a good EQ pedal (Mids up, treble down) and lots of gain, and I can ALMOST nail that authenic neck HB tone, but not quite. It does the trick, but it could be better.
I've thought of getting it re-routed and sticking a neck Nailbomb in, but it's too much hassle for something that does the job anyway...
But sorry, I have zero experience in doing what you're thinking of doing :(
