over-thinking / over-complicating with no real benefit. i'd say, shit or get off the pot.
hydroponics is providing 100% of need in plant-available forms around roots.. .this is why growth is generally faster and easier to fine-tune exactly what exists around the roots in an optimal way -- not saying that has been mapped out 100%, but with a little effort and resources, it is a very achievable goal.
living soil is trying to have that end result around roots, but more complicated / more steps involved as far as any slow release or necessary microbial life to break various amendments down into something the plant can use... in best case scenario, it can do roughly the same as what hydro does, assuming that all that extra dissolved stuff that isn't plant-available doesn't cause unnecessary impediments for roots to take in nutes. Maybe it's got a ceiling of "X%" of hydro.. or not... can't assume either, but is definitely a valid concern without proper research to be certain.
so, they are not really compatible to put together.. sure you can do it... and you can even find a way to make it work, but it's either a poorly setup hydro grow or an insufficient living soil context, lol. 2 wrongs don't make a right.
People engage in all sorts of less-than-efficient behaviour... look at the popularity of bottom feeding, lol, or those really elaborate training methods that end up taking 2x as much vege time to accomplish the same end goals. So, in the end do whatever floats your boat... just don't project magic onto it due to insecurity.
