I thought so too, but the eyes were of Madara and not of Nagato. In that case the eyes are Hanabi's.

Toneri did not seem to be someone with large reserves of chakra, but he used Tenseigan. And Kakashi who had no chakra every time could use Mangekyou. And Obito also used the Rinnegan, but obviously not in the same amount of times as Nagato.
