It's a necessary condition to have Ashura's and Indra's chakra, or rather the pieces of their chakra that encodes the Rinnegan as a KKG. Sasuke has that chakra, which means that he can technically pass on that KKG.

The issue i think is simply limited sample size: Hagoromo had two kids, and those kids had only a fragment of his power. But that doesn't mean that it had to be the only outcome. For all we know, he could've conceived a child with ALL his undiluted power if only he had tried. The same way that Hashirama's powers may have been passed on to one kid. Besides, aren't Itachi and Sasuke an example of great power coming from parents that aren't known to be special in any way?
