Although the punch would / will work why make it more complicated?
Seems to me their are many ways to accomplish this an most go with what works for them.
One suggestion would be to add 2 additional holes to your board (or use 2 existing ones)
drill them first....(these are the registration holes) I lean towards having them some know distance apart and location.
ie .25 from the bottom edge and 1.0" inch apart and offset from one of the edges.. this what when I flip the board I already know
what side I using even before any transfer has occurred.
use the hole to line up your stencil/template/transfer etc....
do the photo/etch one at a time or both side at once. what ever works for you.
I do mine both side at one time. once completed I then commence drilling the balance of the holes.
