I'm with Mark on this one. I'd suggest you think about and consider the hi-output singles first - doesn't mean it's not valid to go the humbucker route though :D
I messed around with an early 80s JV Squier (in the early 80s, and then again in the 90s), I kinda regret it now. I was trying to make it do something other than it was good at. It's still a cute guitar, but its not what it was, and its just not worth the time/effort/money to restore it properly.
I've not tried the higher output BKP singles myself, but if I wanted to push a strat to its limit now, I'd get the sinners with baseplates. Sooner or later you're going to want a strat that sounds like a strat as a contrast to the mahogany/warpig. Perhaps, think about whether it's this one or not... :)
