Batman and Sons universe would be ridiculous, awkward moments when Terry revelations come up but I think normal comics 'verse works better. By Arrow family I just mean like, Ollie and Dinah living with Mia and possibly Connor (I don't even know what Connor is up to these days).
I bet Selina convinces Kon to play pranks on Connor because she thinks he is too goody-two-shoes which leads to Ollie coming around and yelling at Clark.
