So talking about Maps since she debuts as cosplaying as Robin in Issue 119 of Batman.

They did say they'll eventually use Maps in the Robin series, Maps returning again as a cosplaying Robin in solving mysteries, and combining with Damian solving cases like he says in Son of Kal El issue 6.

Think they'll meet in a future issue where Damian is investigating a case, and that's where Maps stumbles in trying to solve the case too.

Seems that way.

Also, wonder how'll Damian react to Maps in a Robin outfit, disapproving definitely, but considering he gave her a batarang and a Robin domino mask, I'll say that he might just insult her saying that she needs to improve her detective skills.

And definitely when Maps and Damian eventually meet again, think it became a thing for the two, hand.

Like Maps hand holded Damian, and put some snot in his hands in Gotham Academy Issue 7. Then in Gotham Academy Second Semester Issue 11, Damian trying to hush Maps got his hand licked by her.

What a weird way of the two interacting but it's funny.
