Is a hybrid Gangplank build now Viable with Rageblade and Gunblade?

I've seen youtubers play Hybrid and and they seem to be snowballing out of control and carrying their team. I was thinking that Gunblade and Rageblade might make a good addition to a Crit Plank build. Scurvy and GP's ult both scale off AP while his Q scales of AD. Any thoughts?
