The manga adaptation for this recently was completely fan-scanlated for anyone interested. Note though that the manga is partially an original story so it might not convey exactly the story of the LN. However, it feels like a good taste of it. And it really just makes me want to read the Light Novel all the more.
As @Korppi as linked, there is an established topic for this suggestion, please consider showing your support in that topic.
It would definitely make for an interesting title to get licensed. I'd love to read it. But, if DxD got licensed then there is most certainly a chance, even of it is a small one.
It is very hard to keep up with the topic when it is about so many books. The accepted method is one series per topic when making licensing suggestions. And to put the name of the series as the subject.
And the first one listed already has a recommendation topic.
