Yes, running the chainring flipped will improve it's life as it brings fresh correctly profiled teeth to the loaded side of the chain. It doesn't help as far side wear at the points, but that should be a non-issue in SS, since there'll never be chains feeding from angles.
Either way, the one best thing you can do to prolong chainring life is to replace chains before they wear too much, and even consider rotating multiple chains every 500-1,000 miles, so you're not running stretched chains until the very end of the total life cycle. I rotate 5 chains trying to eek every last mile out of an old and not replaceable freewheel on my vintage bike. I'm about half way through, or on my 3rd pass through the chains and the freewheel looks almost new. Had I been on my third chain, each used to the end, there's no way it would be this good.
BTW- your chainring bolt head will stick out a bit because chainrings are only counter-bored on one side.
