As a Glow man from years ago and recently restarted using glow ... more interesting than plug and go electrics !! _ I can say this ..
a) Inverted engines prefer to be started right way up - it's to do with crankcase pressure and fuel draw for initial start.
b) Once started, revved a few blips to clear over-rich starting condition - should be fine to flip model over upright.
c) Inverted engines can be more sensitive to needle setting - so careful adjustment to prevent the spitting / cough on opening throttle etc.
d) Tank placement often is poor for inverted engines unless model is designed for inverted.

I like your Idea.. well engineered!
Not trying to shoot it down.. but with a programmable radio there HAS to be a way to program that in...
some kind of MIXING of two channels. and on is just an 0 or 1 choosing when it opens has to be the hard part.
the 61 never did run well upside down.. I flew it a couple times still did not transfer well after an idle.. O|SO I switched back to my Sig53 Aviastar (now that I finally got it back after Sig "repaired" the carburator) it seems to run pretty well. it is mountd semi upside down, head at a 45deg downward. so I am going to stick with that setup for now,.
The FOX miracle plug seemed to help out so I am sticking with that.. My onboard glow driver from HK did show up. I have not tried it out yet.. gotta figure out how to program the TX once I do i'll stick it in.. I might just hook it to a free channel and when I decide i want to idle for a while in air... flip the switch.. but automatic would be nice!

With todays radios and programing it could be set up to a switch on and off with a mix and have a panic on switch.
Now with my interest being bigger airplanes. and gasoline engines all the way down to 10cc's And a big selection of 20cc engines for the 120 size glow airplanes I'm starting to look more at the smaller end of giant scale.
