Back in the day when everybody ran 16's on duallys the popular size was 225/60/16 as I remember. 225/75/16 or 215/85/16 was stock on my 2000 dually. The 215/85/16 is the same diameter as my 255/30/24's so if you did set it up to lay on those or a 225/75/16 you would be all set to upgrade to 22's or 24's in the future. To be honest though, if you are going to stick to 16's I wouldn't go through the hassle to lay out on that big of tire. Before I was body dropped I ran a 215/70/16 which was a bit smaller than stock but still was a suv/light truck tire as opposed to the the 225/60/16's. They were not load rated as c, d, or e, but still held some weight.
Just depends on the look you are going for, do you like small tires on small wheels or big tires on small wheels, or small tires on big wheels.
I can't say for sure what size tire will allow you to lay frame on that body style dually but I am sure someone will chime in.
