You can, but, as Warp said, the illumination would be at least slightly
incorrect.

Yes.

Yes. When you re-use the values, it will still generate more if necessary.
You can even use save_file and load_file at the same time, and when you
render the scene over and over again, it will keep increasing the total
amount of data that it has. It will re-use the old data and add more data
to produce a more accurate solution. You can use "always_sample no" if you
want to only use the data that you load and you don't want any new samples
to be taken.
