I’ve got a 2nd and 3rd edition of the Jobst book. Wish I’d bought more copies before they went up in value. I’ve tried other books, but his one is just so simple.
I did upgrade to a shop quality wheel stand, dishing tool, dial indicator gauges etc.
I would, and have, 100% do a swap. I bought a used DT240 rear wheel on a Stans Olympic 26" rim. I despoked the hub and built it onto a 29er wheel, and then found a particular year XT front hub could use the same spokes as the DT rear when building with the Stans olympic. so I got a $15 XT hub on clearance and made a sweet front wheel out of it.
Wheel building is not magic, it’s just something that isnt that hard if you’re very methodical. Do what Jobst says, in the same order etc.
