That's exactly what I was doing when I modded my Squier! Trying to get a different sound on the cheap... I'd been a strat player fronting a 3-piece for years. Then I was fronting a 4-piece where we added a "lead" guitarist so that I could concentrate on front-man duties.
We were playing blues-country-pop-rock originals (think Tom Petty raised in Devon and living in Surrey!). The tele seemed the way to go initially - an electric I could strum like an accoustic, and I found this Squier real cheap 2nd hand. It was great.
So we had me on a tele, and the other guy on a strat. I started feeling we needed to warm the sound up a bit, and I thought "Keef Richards has a neck humbucker... that's the answer". So I got the chisel out, etc, etc...
The neck sounded great - a bit like a humbucking guitar! - and the bridge sounded great, but no way of using them in the same song (or at the time, even in the same gig! - being frontman, I couldn't keep running to the backline and fiddling).
We reached the conclusion that I ought to be playing a Gibson type guitar in this band, I acquired some Epi's second hand, and I never really used the Squier again!
Sounds like you're the same as me - a "fender" player wanting to move in to "gibson" territory as well. It also sounds like you've got another problem now though (reading the other thread as well) - you're after a nice warm humbucking tone, but falling for a PRS with soapbars in. It might be that the P90 sound is what you're actually after, but it also might be that that particular PRS is one of "your guitars" (ie you pick it up and it's "the one") and it's distracting you from the humbucker quest. Both routes are probably right, but, it's expensive to follow both!
(I really thought I had all this solved a year or two ago with a Line6 Variax, which does do what it says on the tin, but we've bought another 3 guitars and three sets of BKPs since then!)
