Well, if it changes the sound of my BKPs then I don't want it. If Tim would wind pickups knowing the change caused by the cryo treatment and anticipating it, that might be different.
I do like Blue Steels on my EVH, but not on the Les Paul.
I have two cryo valves, a KT77 and a 6L6, and I like the 6L6 but not the KT77.
So I think it's like always: things need to make sense together. You can't have DM Blue Steels, and George L cables and cryo pickups and cryo valves, that just becomes too much treble and too fast, too.
If you have a muddy guitar though, then maybe cryo'ed pickups are just the right thing to fix it...
