should I combine Baby AU and OT4 baby au?

I know I drew the ot4 love children just for fun but... I really like the OT4 baby au character designs and I want to draw more about them!.... but a part of me thinks its too confusing to have two different baby aus thats why I never really talked about them outside of patreon! my normal baby AU is of koneko [krkn baby girl] and is usually of her being a baby and krkn being parents ! My Ot4 baby au is about the love childreen as Teenagers

edit: so it was hard to fit everything into choice 3! so I would change the characters a bit so kuroaka child would be biologically krkn's child and would but koneko's brother! same with the twins instead of them being bokuro Id change them to be biologically bokuaka twins and kirkira's brothers
