Yes, that's one of my concoctions. The only difference is I add some microbes in the mix to enhance the breakdown. I use worm castings which, in my
experiments, worked better than LAB and even the more standard suggestion of leaf mold soil. Plus it's super easy to access for me since I make the castings routinely.
I think the fermenting step helps make it shelf stable as well as enhancing the breakdown of the material. I've had some of my stuff now for years.
I have both a veg and flower "Swamp Juice" as I call them which is a mixture of various extracts I have on the shelf. Bananas are good in flower as are pumpkins, but I also do a fruit and flower mix which is exactly what it sounds like, fruits like apple, blueberry, banana, cranberry, etc., really most anything will work. Same with flowers.
I'm planting a lot more flowers in the yard for this exact reason. Big showy ones like daylily and peony for example because that's what I want to produce in my other plants, big showy flowers.
