Dude, that is insane. I love the ingenuity, but it is insane. And even with the metal fab that you're going to have to do to bring it even close to being in compliance with the rules, it still won't get there unless that fuel cell is FIA certified. I strongly suspect that is set out in the insurance policy, and thus why it is so specifically set out in the rules.
I hope this works for you, but be warned, here's the response I think you can expect from El Lammo: at MSR-Houston, one of our Ichabod Crane impersonator drivers accidentally turned off the car twice with his knee. When I installed and wired up the switch panel (including the ignition switch), I never in a million years imagined that one of our tall-ass guys would be able to even reach the switch with his knee, no less flip it off with said bony knee. But it happened. When we were pulled into the penalty box, and I was having a calm and interesting discussion with Senor Lamm, his point to me was this: when he dies in a ball of flame caused by him hitting that switch and causing a crash, how am I going to explain to the widow and orphaned children of this driver that I knew about this switch being in the wrong place and did not force you to correct the problem?
I had no savvy response other than, yes sir, we will move the switch right away.
Now I'm not a very clever guy, so maybe you have a better response in mind when Jay asks you that same question in regard to this setup. But I see about a jillion things that can go wrong with that setup, any one of which results in a permanently disfigured driver.
That said, I love the creative thinking. But if I wanted to make sure that my car passed tech the first time, I'd move both of those devices far, far from the driver. Cheers and good luck.
