Sure it's doable. Bear, Hill, Pearson and I'm certain several more I'm unaware of have done it. No doubt Ferguson could do it.
I'm not a waterfowler but my brother-in-law does it seriously, (he's also a bowhunter), and after speaking with him he thought a recurve would probably be the easiest to handle in a pit or blind. Mostly because they are shorter. My personal opinion is I wouldn't go any shorter than 56 inches mostly because I don't care for bows any shorter than that. Not that they aren't effective, they are. I simply don't shoot shorter bows as well as longer bows.
