Good to know that the increased FOV made things better for you and looking forward the the setup photos.
The reason we can't really go much higher with the FOV is that view side-effects involving the ships' models themselves start to occur if we go too far. In other words, you start seeing the inside of your ship's model. I have made a quick test using the core ships and a 90deg FOV and I think that 90 degrees is about as high as we can go without excessive model interference. Higher than that will require repositioning of the internal view camera locations and of course, testing at various FOVs and screen size ratios and for every single ship to ensure that no other side effects occur.
As an example, here is a screenie of the core Python's side view wilth 90 degrees FOV and 16:10 screen aspect ratio. The bar you can see at the bottom is part of the Python model that is not really meant to be seen and is indeed not visible at 80 deg FOV. Note also how the HUD missile info is already obscured at that FOV as a result. So we need to be careful before we apply any changes and I would not expect too much of a jump from the current limit of 80 deg..
