I am thinking that will be broke in a couple of outings. From the water / flex to just deck pressure. A standard pontoon width is 8.5 feet. So I guess if you want to park it easily in a single bay garage this possibly makes sense. Seams like a PItA for 1.5 of width off the standard. One last thing - slide outs on a Moho are finicky at best. I cannot see adding this aggravation into my boating.
