Then shortly after, Obito confronted Konan as Tobi and stole the eyes from Nagato's body so that he could transplant them into himself? He's talking about the "false" Rinnegan Konoha possessed through the original Animal Path. Jiraiya took down the animal path and sent it to Konoha before getting killed. And even after getting killed, the Animal Path still had the Rinnegan pattern in its eyes. So it's puzzling why Konoha didn't try and transplant those eyes.

My personal opinion would be that the transplants wouldn't work, since they are not the original Rinnegan eyes. However, there's no way of knowing that for certain. So Konoha should have tried transplanting. But I suppose they thought there was too much risk in that.
