Yeh, failed experiment was what I was thinking, even the visard wouldn't have survive if Urahara hadn't give them a little of quincy reiatsu as he told Isshin. But it had to be possible, I'm hoping they send some info our way when they explain that whole masaki hollowfication passing to ichigo while fusing with his zanpakutou.
