I think so, though maybe start off with introductions before the test. And not use a jutsu to conceal yourself at first XD I mean for now we have no sensor of any kind to my knowledge. XD Have the test focus a little more on teamwork and working together than simply testing our individual skills. You'll have time in the future to test and gauge that. Also being that Nagato is your nephew you're likely to have a fair grasp of him as an individual already. Unless he's the jerk kind of Uncle who just doesn't know crap XD lol
