Nitrous plumbing A1A...??..

The only major flaw in your plan so far is that you are building a fuel system capable of running at the maximum level of your nitrous solenoid. Once you have fun and get used to that lower level you are planning, and see how easy it was, you will wonder what more feels like.
“Heck, the fuel system is ready. More octane, a little more timing retard, it will be fine.”
Everyone does it. Good luck with your self control. Of course, my car was a dog to begin with so I was way on the safe side with much less fail safe measures.
Looking forward to your first impressions review. I predict a huge smile or grin. The one that comes right before “hey, watch this.”
Yes this is kind of why I'm building the system up from the beginning. No sense wanting more and not being ready for it. I have far too much of an addictive personality and know myself too well...
