You mentioned that you have two positions left on the coolie hat -- are you not using your pitch trim on that switch?
One possibility is using a couple of switches for engine start. I have two switches on my stick grip that must be held down together to engage the starter, which works great. I have control of the stick and my other hand on the throttle. It's better than trying to hold the stick back with my knees. By having to hold down the pinkie switch AND engage the starter with another switch, it can't be accidentally engaged in flight.
I also have a push button on the panel that says START but, until just a few days ago, I had never used it. I finally did, just to see if it worked. It did.
