I want:

-cute domestic adult Solangelo

-an older Livvy standing up to people teasing her because she has two dads

-Solangelo with more children (for this thing's sake, Liam and Elizabeth)

-Nico teaching the kids Italian, Greek, and Latin, because they should know the basics

-Will teaching them how to play instruments and how to treat an injury because priorities.

-Will not being able to come home one night because of work and all the Solace-di Angelo kids crawling into bed with Nico 

-Will coming home at five in the morning to find his entire family curled up under the blankets

-Nico being overly suggestive that Hazel should have kids, too

-Jason being a super obsessive uncle because SOLANGELO BABIES

-Both of them being worried about not being good fathers because they spent a lot of time without a father figure

-All of the Solace-di Angelo family getting into the bickering wars over some arbitrary thing, like whether it's smart to double-shelve books (Even baby Elizabeth, who just giggles)

-Livvy being super protective of her siblings.

That's what I want.
