Hagoromo implied that the Transmigrants can choose their host. So there isn't nearly as much weight behind the Senju/Uchiha clan being picked as it seems. It's just that both clans seemed to fulfill their ideology the best. Or perhaps these clans allowed the Transmigrants to achieve the most, the Senju and Uchiha were the strongest clans after all, and what better way to change the world than to be the leader of the strongest clans?
