Quite frankly, I think you don't like that guitar at all. It all seems like. You had it back for sale two days after you purchased it since you'd gotten a PRS (?) and now you're looking to strip it down to the bone to rebuild it in a completely different fashion.
Don't know my friend, do yourself a favor and evaluate well all the options before you embark on something for which you'll be cashing out a lot of time and money, may be even regretting it in the end.
One last question: Do you really like the feel and sound of the guitar? If you do, then it may be worth it, if not quite convinced it is something great, then you're probably better off thinking about getting something you may like better right of the gate.
I know it's expensive to mod things, and lowers their resale value, which is why I asked. I eventually decided out of the PRS, since it wasn't my style (even if the price was pretty good).
I'm just not used to the trem and neck - I keep bending the low E string all the way off the neck while playing, even though it's the best feeling neck I've ever had. And the trem is great, but it just makes it hard for alternate tunings, and I don't have the budget for two guitars. I'd get a SA or RGA, but I don't like the look of the SA headstock - I might consider an RGA, though. Or just get a tremol-no, if they're all that they can do.
I'm just worried that if I keep this 'if it's not inspiring, sell it' attitude I'll never find a guitar I can like enough to keep and mod. The feel is great, but if I could sell it for what I'm asking I could get a Gibson LP Studio Lite which looks real neat and I've been eyeing for a while - my only concern with that is how heavy it'd be compared to the S, and the brokerage costs (god damn canadian customs).
Does anyone have any experience with tremol-nos? If they really do work well, and if the guys who enquired don't get back to me, I might just keep the thing and fit one in so it can serve as a fixed bridge guitar when I want to play drop D or stuff.
