I did actually request them to make my work official, if possible in any way.
They said they will review my last uploaded patch and decide when the license for the game comes into question.
In other words, if it does happen, it will take a good while. I'd say anywhere around 2-3 years. They have the entire triology of IroSeka before deciding on their next Favorite game, and I wouldn't be surprised if they decide to do AstralAir next.
I personally wish to translate this game officially if possible as that would mean a lot to me, but honestly speaking I wouldn't be surprised if someone else decides to get something done before NN as an official translation would definitely take some long time.
