Yes, I've re-used a handful of 12-sector packs formerly used on a PDP-11 in an RK05 without any issues. I suppose it might be possible that if the alignments of the Diablo in the Alto and the RK05 used to write the pack originally are off by enough that there could be some odd issues (old data left halfway between the new tracks?) but that's purely speculation on my part. Bulk erasing certainly couldn't hurt.
