Outside from the fact I think that Keepers are a bit more monogamous than this culture seems to be in contrast to the Seekers who seem to be more polyamorous... so I don't know how well that would work ^_^; Also they seem to have big families which take care of their own averse to the Keeper's more isolationist feel... I get the sense from how they're written they wouldn't necessarily take in family from another tribe so tending to the elderly or left children would actually be more of a thing.
That said there's a lot of interesting ideas here.
