The biggest problem I can see is that apparently the fan translation is already approved by the author, so people might be upset if it's shut down in favor of an official release. Or it might become another Rokujouma, but that means it would be less viable commercially.
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.
The new license reminded me a bit about this so I thought I'd give this one a bump. The new one is about a guy training a gal or something while Hiota no Kanojo is about a girl that's trying to learn about eroge cause she likes the protagonist. Ecchi Romcom Justice.
