will you still think of it as a Canonical story?
To be honest, if it's not 18+, you're probably barking up the wrong opinion tree. The idea at hand you've managed to "procure" would most likely work better as some kind of dating sim but may still leave older; and I assure you that the majority of whatever audience is playing this game would be older, individuals pissed off and wanting more. As I'm sure you've already seen multiple times over, this works great for creating a sequel and you can probably fill that with some 18+ plus material that will satisfy the fans.
The real problem you would have is that
intellectual property in Japan is solely copyrighted by the original author, which in this case I imagine is Jun Maeda. So unless you wanted to be hounded after by lawyers if you put your name
anywhere on the material you've produced I'd stray from the idea. If you don't copyright the material that will basically lead to a few rip-offs that may include 18+ material or improve on your idea which would in turn end up making the rip-off more popular.
Then again it could turn out to be a VN of epic proportions and you may just win a few buyouts in Japan.
To answer your actual question: No, I would not.
