Those Wilde L-45 pickups sound awfully sweet. I looked up a couple/few videos of them, and was impressed. Good players, though. Gotta give them credit.
I like those hipshot hardtail bridges. I have one on a project right now that I'm looking forward to living with. If it was me, I'd go straight to that, rather than mess around with the vintage Strat hardtail, but that's just me.
The "Megaswitch" or "Superswitch" can be wired to give you the bridge/neck combo, but you'll lose something else. There are seven possible combinations of three pickups, assuming you don't do the coil cuts or phase reversals or series/parallel torture, but there are only 5 positions, so you gotta figure out which ones are most important.
