Does anyone know of any novels that do this which I could look at as
examples?
There may be a reason that it is so difficult to find examples of the style.
It is probably far too difficult for readers to accept 3rd person present as the point of view.
How does 3rd person present help you tell your story any more than the normal and accepted 3rd person past? Let's take a look at an example of 3rd person present.
Walter is walking down Groves street and he hears a car come around
the corner. Walter keeps on walking, staring at the lines in the
sidewalk. The sound of squealing tires draws his attention and his
head jerks up, just at the car bounces up onto the sidewalk. Walter
sees the front left tire pop on the curb, but the car is racing
directly at him. He jumps to the left and falls to the ground. The
car races by and smashes into the building, narrowly missing him. Walter's mind went back to another time he had to dive for cover. He was serving in the first war in Iraq. Tom had been standing next to him showing him a picture of his fiance when the rocket propelled grenade interrupted their conversation. Walter had pushed Tom to the left and then the terrible explosion. When Walter woke up two days later two shattered legs he had asked about Tom. The doctor hadn't replied but just walked away. The sound of the car door opening pulls Walter back to the present.
Is that even different enough from the following to matter?

Rules or Guidance
Some rules need to be broken in order to move to something new. Others rules are simply meant as guidance to commonly accepted practices that work well.
Just something to consider. Good luck.
