Maps would definitely have worked. I think Damian shines best when partnered with someone slightly cheerier then him as seen with is great dynamic with Dick, Steph and Jon. So maps is perfect and fits the bill.Sadly im not sure we will see her ever again unless Gotham Academy comes back
We can dream for Gotham Academy Year 2 one day.
Personally I would relaunch supersons under Tomasi renamed 'superfriends' so they can also focus slightly more on Kathy and Maya. I think a team of Damian, Jon, Maya and Kathy would have been really good and could have appealed equally to both girls and boys. Idk why but the idea of pairing Damian and Kathy seemed interesting to me. My logic was that it would have been very interesting and probably humorous to see how Jon and Maya reacted.
