Honestly? I'd probably snag the cheapest set of burstbuckers or other gibson oem buckers and swap them in. If it's an improvement then you'll know where to go from there. If it's not, then the guitar is probably never going to improve much.
The pickups I would choose:
1. Dimarzio 36th Anniversary PAFs - Vintagey, clear, not scooped like Duncans, and distort quite nicely
2. Seymour Duncan Pearly Gates set - wound for Billy Gibbons, Warren Haynes approved.
3. Dimarzio Air Norton & AT-1 or Air Zone - Higher output, but not insanely so, more modern
4. Seymour Duncan Seth Lover set - unpotted for old school tone
5. Dimarzio EJ Custom set - a mix of PAF and Filtertron
Personally, I don't go for boutique sets. YMMV.
Out of curiosity, do you consider Bare Knuckles boutique? They're a little more expensive than the Duncan/Dimarzio classics, but not outrageous by any means. I don't know if it's just my exact configuration, but tonally I'm happier with them than anything else I've ever tried.
