Back when we used to actually get a lot of snow here in MN, i would setup my 4100 with the 47 blower with the wheels in the narrrow position and it was fine (turfs are slightly under 48" wide in narrow position). Nowdays, with the light snow we get, I just use the front plow instead.
Another option would be to add some angled "wings" to the sides of the 47 to sweep a slightly wider path.
In terms of adapting something to the front that is wider, a Deere 59" might be the best starting place. Although the mounting scheme is all different (you would have to have a custom mount adapter and perhaps driveshaft(s)fabricated), the PTO rotation and speed should be the same, so no gearing changes required.
That 4110 might not have enough power to spin the bigger blower in full-depth, heavy wet snow at full speed, but you can always slow down to match the tractor power.
