i wouldn't bother.

the faq answer:


doesn't even consider dviselect (___old___ technology).  since you're
using book class, i'ld go for the simplest of them all, \includeonly

the one significant problem is that out-of-chapter references are going
to dangle ... but that's going to happen whatever solution you choose:
it's implicit in your chosen procedure.  (i think your procedure is
sound, i merely want to point out this slight irritation.)
