Hi judiray, have you had a look here? Unless the specs have changed, this link has the layering of several plb mattresses including the beautiful model.

Some of your layering looks different, instead of 1" of extra firm latex at the bottom yours places the 36 ild 6" core at the bottom. Your suggested construction also takes away an inch of 19ild on the top but adds 2" of 24ild in addition to the beautiful’s 2" layer. Being further away from the 36ild base ‘may’ make your version a little softer in terms of compression while the thinner 19ild may make the surface feel a little firmer. Subtle differences and no way to really guess accurately. It could come close or may not feel the same at all to you.
If there’s a way for the local place to make a mockup using that layering for you to try before building it might be the best option to make sure. Latex reacts in odd ways sometimes at least when I was trying them out in the store. Amazing how much difference a few inches of softer latex clear at the bottom beneath the entire mattress can have on the whole works. Maybe another option if possible, if they could do a zippered ticking giving you the option to remove layers and rearrange them at home?
