I have seen recommendations for using coco to modify soil to make it a bit better drained, as I recall one of the major seed merchant online recommends it as a standard approach. It probably works, but I've never used it that way. Perlite also does something similar, and most growers that use coco add perlite to increase drainage, my autopot mix is ~40% perlite.
I can't help you with putting hybrid soil mixes together as I do not grow in soil, I grow in coco, and know nothing about the products you list. However, I still think you are better off either sticking with a full organic soil grow if that is your real interest, or go soil less either with coco, or with ProMix HP myco or equivalent peat based mix which is a bit more forgiving than coco. Pick an approach, look for grow journals here that use the approach you would like to try, and carefully follow the lead of someone who is consistently successful. Don't try to mix and match portions of what others do, at least not until you have lots of consistently successful grows behind you. Each different approach that works does so because it achieves a balance among a lot of different factors, and you screw with a successful approach at your risk.
If you don't have the time or inclination to do the full super soil approach, I think you would likely be better off going soil less , but different strokes my friend, whatever cures your bud.
Good luck with your grow.
