What are ghost style limbs? forgive my ignorance.
Going from 2 lams to 3 or 4 or 20, really shouldn't change the stack at all if they're all the same material. The core material has alot less affect on a wood bow draw weight than on glass based on my experience and what I've heard about glass bow core woods.
Back with hickory or bamboo ... they are both epic and you will be happy.
