Continentalness, Depth and Erosion from a Custom Density Function

Wassup Smart People :> I've been trying to make a datapack that utilizes custom World Generation to create an ocean world dotted with islands, for which I already have a suitable (if scuffed af) Density Function (the one attached to this post). However, I encountered a slight problem when it came to biome generation (since the Density Function is also used inside a custom World Preset): while I can still just use the vanilla Temperature and Vegetation density functions, I lack usable ones for Continentalness, Depth and Erosion (the terrain is, of course, custom, not a modified form of the vanilla one, but it DOES use a few noises from vanilla). My question is this: How could I (if it's even possible at all) go about extracting usable Density Functions for each of the worldgen parameters from my own density function?
