How to have more than 8 sims NATURALLY with Kinkyworld

[Vester7]

I've posted a question on the Kinkyworld forum but no responses yet, and this question might be applicable to a broader audience if I need mods aside from Onikikay's work. So, as the title suggests, with Kinkyworld, can one naturally have more than 8 kids IN THE SAME HOUSEHOLD? In my case, my custom household already STARTS or was designed with eight teen to adult sims (a large extended family) but I want to have some more, naturally. I don't want to use NRAAS options of "pollinate sim" or "add sim", I want to get a new sim via woohoo actions - the good ol' natural way. My accompanying mods are NRAAS master controller, debug enabler, story progression, portrait panel, relativity, careers, error trap, and mover (I have modified settings of NRAAS mods to not conflict with Kinkyworld as stated by instructions: e.g. overwatch settings, deferencing...If I need to do more than that please tell me). I have already set in NRAAS to allow more than 8 sims, have unlimited number of pregnancy's (set value 0 as stated by NRAAS mod), and a maximum household of 20 people. I really don't know how to go any further. Please help guys.
