I think I know the obvious answer here, but I'll ask anyway.
Can a vent pipe be routed down? Due to a sloping roof line, once the vent reaches 6" above the flood rim, it will have to be sloped down into the existing vent stack. I know that liquid will fall either direction but gases could be trapped.
Am I going to have to make another roof penetration and put in a new roof jack?
