Okay okay so hear me out, what if Witch/sylph were the creators (Maybe changers but that sounds kinda silly), and heir/maid were the inheritors (Maybe the possesors or owners but something along those lines). Since heir and maid both show some kind of ownership and they both sorta "are" their aspect (John becomes air to escape jack and aradia already being dead). And since sylph and witch have alot of similarities (but I'm running out of space and don't have the room to explain it I'm sorry)

It’s a popular pair, and it was originally a pair I headcanoned, but nowadays I go with Maid/Sylph and Witch/Heir because they’ve shown way more similarities. Both Maids and Sylphs are talked about in mythical terms of some sort as Faes, and have consistently been the ones to pull off acts of resurrection, specially of self-resurrection, whereas Witches and Heirs have a connection to Magicians and Familiars, as well as a more consistent manipulation of their Aspects.
