Sweet build! Those pups are ok, and if you look long and hard on the bay, I'm sure you'll find one eventually. But for steel inspired guitars, you really can't go wrong with a tele. A plain old tele. Seriously, those things were designed after lap steels. The traditional pickups have those head splitting highs that modern guitarists hate and steel guitarists crave, and a good tele with stainless or brass saddles and a well cut nut can sustain for days.
