I bought a 5H body a while ago, fitted a Status graphite neck, made a vintage SR preamp circuit (from PCB's sold by Uncle Fluffy), removed the blade switch and stock preamp, and swapped pots. The pickup were wired in parallell. It sounded a little harsh and clanky before this mod, now it's really smooth. I wouldn't say it's quite vintage, but I like it a lot better than stock.
I recommend keeping the stock preamp and pups, if you plan on swapping them, as it might be easier to sell if you leave the option of fitting the stock system again.
