It's how I did it, when I still trusted the spokes but the rim was dead. Lacing is monkey work, tensioning is skilled work, I don't like paying pros to do something so simple.
Lots of people say "build it yourself", I could learn but I take mine to the best wheelbuilder I know, even if I do an adequate job first time it won't be as good as his (and neither will most pro builds). It's a lot of effort to expend on an inferior job tbh when £10 gets a superior one.
(unless you believe the first wheel or even the 10th wheel you build will be absolutely perfect, in which case, good luck!)
If the wheel's generally clapped out then it probably makes sense to replace spokes, though, on general principles- always a balancing act, you might be wasting money replacing spokes that would have lasted for years, or you might be wasting a new build on spokes that won't last.

ERD's need to be the same....
Or close, anyway.
