Good effort. Well done, what patience!
I would worry constantly heat up the same sections again to just fit a few more balls?
You will save on the stencil, but imho it is safer and quicker to just order a stencil.
Anyway, those are my 2 cents. I hope I don't see another case like this for a while.
Phone IC reballing is very similar. If you do mobile repairs, this is pretty straight forward.
