Sure thanks very very much Guitarians!

Hi Guitarians, I am making my own acoustic guitar and it is nearly done however I have not cut the circle hole in the body. Instead, I was thinking about a non classic circle hole pattern. However, I have only a drill and some bits like different size tips, hole saw bits (in different sizes). So my question is about a pattern with only these (drill) bits. Do you have any ideas or templates? See the attachment for an example
