Anything is possible. The only problem I see would be how high out of the water your poles would be. I'm imagining your bow as being maybe 3 ft out of the water (I may be wrong). You're going to catch a lot of wind. Not just with the boat, but with the lines too. Your goal it to get those rod tips as close to the water as possible. Without extremely long poles (12-14ft or longer), your poles would be at an extreme angle. I would say if you're thinking about trying it, get the absolute shortest one you can find.
I've seen several set up on pontoon boats. Just figure out the distance from the rod tip to the water, and you should be fine. It'll take a little while to figure it out, but if you don't give up on it. I'm sure you will be glad you put them on your boat.
