My son has a First Act guitar. Call it a Franken-Strat-o-Tele. Bolt-on Fender-style maple neck with a rosewood fretboard and a 3-and-3 Gibson-style headstock, Tele-shaped body with comfort contours. Vintage-style 6-screw bridge. A bit like this, except black:
And, as built, it had a single bridge humbucker. And it's routed for a single bridge humbucker. And, in a fit of curiosity, he took it all apart and lost lots of pieces, including the pickguard, which being Strat-style, had all the electronics but the jack.
Consider this. A page full of pre-wired pickguards. I'm considering getting one of them. I'm thinking white-on-white sss to make it as Blackie as possible under the circumstances. A $50 GF neck might follow soon after. But the problem is, as mentioned, a lack of route. A friend and sometime commenter here has offered the use of his sawdust-creating technology to excavate the swimming pool route. So, do I return it to being a one-pickup 'bucker, or do I carve it up to add neck and mid?
