Doing A Walking At New Moon Options

I know this is a stupid thought, but what do you guys think would occur if one were to do a walking at New Moon. I figure a disaster. but what if one had crossed the Abyss/gone into GANZIR? Would the priest have the capabilities to take on a gate at the time of the Bitch of the Black Moon?

Honestly, I was just curious of the possible uses of walking on New Moon, as a way to learn of the enemy and their strengths. As I have not done a walking at all, I KNOW not to try this. But down the road it might become neccessary to conquering certain internal demons that lie in wait. By demons I mean the primal aspect of the soul that is interfering w/ the souls Evolution at the most base level---the final link w/ Azag-Thoth and the mother Tiamat. The way I look at it, the internal demons are as much a part of you as your arms or legs, so one MUST take control of these demons and destroy the external demons. Its just a thought.......
