It is always easy to lengthen your sidestays. Just put a shackle there (on both sides !)
It is best to have some safety margin with the staymasters. Adding two shackles will allow you that. Don't worry about the forces on the sides stays these are low enough to handled by any normal sized shackle.
Started at top centerline of hull in line with bridle tang.
Took this reference back to where I could touch top centerline of hull near transom. That turned out to be almost exactly 3 inches forward of the transom or about 2 inches aft of the edge of the inspection hatch ring.
Does this sound reasonable?
Sounds a reasonable starting point to me. Try it in that position and see how it sails/feels
