Yes that would be an ok combination but maybe get to know the yopo alone at first. You can dehusk by bending the seed; the husk should break on one side; bend opposite way and husk breaks on other side and each half can be pulled away from the bean.
You should roast them as they lose 1/5th their weight in nasty fats and oils.
Also; freebase before vaporizing. Soak crushed beans in "clear" (surfectant-free) ammonia 20 minutes, remove from the bath and put under a fan; then smoke when they have dried completely. This is great for smoking as there is no excess matter.
Or you can freebase with ash, calcium carbonate (makes eggshell), etc like any yopo tek.
You can also do a crude extraction with Isopropyl alcohol after freebasing and evaporate over more beans or maoi mixture is great.
My dog enjoys MAOI before/with the vaporizing of his beans.
