Assuming 7.5 rise with 14 steps and putting in a 7.5" rise with 3.5" run - taking out the spiral and installing a set of access stairs 4400.00 if you are in metro Atlanta. If you are serious I would get you and your wife to try out a set made like that. I have built several within a block of my house that you would try before you buy. Looks like with L shape access hole you have a way to reuse the handrail and 2 footprint options which is good.
