Once I get it trimmed up for cruise on a long flight, I pull my legs up and lock both ankles behind my neck. I learned this pose from Jerry Marstall! 😊
I recline 30 degrees in my Dragonfly, the calculations are all average numbers you can refine them for specific areas if you want. No it does not take leg position into account. It just illustrates that you do not need a stiff foam. Temper foams are different as the push back changes with temperature.
For me the spot that gets me the most is the back of my heels resting on the canard. Especially after 8 hour flying days. In conventional planes it is the sitz bones.

So do you stand on your seat or have an unusual seating position?
Does this take into account leg weight distribution ?

Simple elegant solution low push back foam.
So my estimated average seat loading is: 220 lbs/ (20” torso + 10” seat) * 12” wide = 0.6 lb/ in2.
So to sink in I would need foam that could not support estimated 0.5 lb/in2.

Corbin, your need has a very simple solution, one which will not make the nice material to large nor cause it to be full of wrinkles.
Change the foam density from it's current one to one that is softer. This will A. keep the exact same shape that your current seat skin's are fit to. B. Eliminate the need to store heavy items upon you nice new material and potentially cause premature wear/tear C. Enable you to get in, sit down, buckle in and go flying. Life back to normal.
There are foam densities that can protect an egg and there are foam densities that can protect a big fat ass and everything in between. They simply put in a density that is to strong for your needs. Shape can be 100% identical but the density will allow you to sink to your preferred height without the need for all this sanding, weighing and so forth.
