For anyone interested. There is an available OV9653 (the same camera sensor, same connector) but comes with a 120deg fisheye lens instead and it works well. It's hard to find and a bit pricey, but if you need it for your application, it does exist.
The other method is to use an add-on phone lens, which would require a modified camera shell where the external lens can be screwed on. I noticed that these external add-on phone camera lenses have a standard screw size, so one modified shell design can allow for interchanging those lenses.
One view with OV9653 with 120deg lens
Two add on lenses that work well too, albeit losing some of the image peripheral from lens obstruction.
The original and the alternative camera sensor.
