The Rinnegan can absorb any Ninjutsu. That's what I've read so that's what I'm going with.

@MIGShinobi, when was Nagato outsmarted by Jiraiya or Kakashi? He beat them both while sending chakra to six individuals while he himself was an emaciated cripple. Even Naruto basically lost to Nagato. Naruto only got out of his jam because Kurama, which is brawn, not brains.

Also, I looked at your panels. His shield did change size. But all it did was go from base, to smaller, to back to base. That could honestly just be the jutsu starting to weaken and then Itachi forced back to full size when the snakes came.

In any case, even if it could change size, to say it could change its shape too is really baseless. It never changes shape.
