Can we bring back enemy honours?

I just played a match where a Kat deliberately afked (I checked her match history and she has done this for two games before this one). A few minute later, the enemy Lux asks if Kat had afked. We responded yes and told her about Kat's two previous matches. She said she would report Kat after the game.

Fast forward to the near-conclusion of the game, we played the game very well and managed to win 4v5 (Kat reconnected a few times to int, and unfortunately one of the times she came back was just when we won the final team fight). After the fight, Lux still says it was a good game and that she would report Kat still as she hates people who afk and int.

If my team and I could, we would definitely honour the Lux for being humble.
