My two modded Strat copies:
Gear4Music:

Started life with shoddy pickups, black with white PG, new pickups, added Neck-On Switch, Clipper Circuit, new knobs and new PG.
Charity-Shop Parts-O-Caster:

Started life Natural wood, no electronics, one working pickup, strat shaped black PG. Took lots of filler, but it's now ready for the respray before wiring it all up.
Just go nutts, you can do what the hell you want. Like people have said, they're a blank canvas!
