If you want to go ahead Green you just have to deal with Gyunei trying to gun you down with his remaining funnels while doing so.

Also I don't think you'd get there in time and they'd have sufficient power there anyway besides the fact that Donna doesn't have any way of getting there quickly. Sandrock would probably be better off dealing with the baund dac or forcing Martin to yield. I don't think going up against Gyunei (I keep typing Glemy...) would be the best choice out of everything.
