Personally, I would not give away soap that might cause plumbing problems due to bits of beeswax. I have had to unclog too many pipes in my lifetime and would hate to contribute to such problems for other people.
Also, even if you tell them ahead of time, the first time they run into a blob of solid beeswax in a bar of soap, they may be so displeased with your soap that they may decide that artisan made soap is 'bad' and never want to try it again. It's bad for business (not just your own.)
I would, however, save a bar or two to test on my own, and probably rebatch the rest via HP. If you grate the soap, melting the solid bits of beeswax will be easier, especially if added to an HP batch of new soap batter. So rather than trying to rebatch the whole batch, I'd grate a few bars and add the shreds to a larger another HP soap batter while it is still heating. This ends up being confetti soap and can look really quite nice, depending on the color combinations and so forth.
