I see now. Trying to model that tower would be very time consuming and honestly with as close as some of those elements are together I think you are right in just using the obliques photos for inspection.
Now I see that you would like to blur the surrounding area to conceal other property. Correct? I don’t see why you need to do that unless explicitly told to do so. That information is already available via Google Earth whether they like it or not. At least we can give them the option.
I would use a program like GIMP to manually blur any necessary details. I personally use ACDSee and it will allow you to batch edit, but more importantly the images are in more of a film roll listing so it is much easier to blur a couple of spots and quickly get to the next image. You can breeze through 50-100 images pretty quickly.
