Good one, I really like the mod to the pic!
No, I think youve got it a bit wrong. If Pain was using a wind type attack or some force other than gravity I think your pic would have been possible,but unfortunately, his attack repels all ninjitsu attacks. If that could have happened what you indicated, all of the other Byuukagan users would have been able to break through or at least repel some of Pains attack, which is not the case.
