Chances are you could make it if you do everything quickly, but that doesn't sound like much fun!
Are you staying at the Poly? If so, it would at least cut down on extra travel time since you're already there. We had a 30 minute wait last time we ate at Ohana, may want to consider that could also happen on your morning.
Me personally, I don't like to rush, especially for FPs or breakfast. You can eat at other places for breakfast than Ohana but you can't experience anything else like FOP!
Have you thought of eating breakfast at AK? Tusker House has a character buffet, and although it's QS, Satuli Canteen has breakfast and it's in Pandora.
