Dang, I must be one heckofa nerd if I think all this is cool! Well, so be it! I guess the shoe fits!
I'm tempted to try a fixed to get some of this challenge at my 70 years old and currently less toned knees and thighs. I can imagine finding a saddle position which works with a chainring pair to do "level flight" and to climb as long as I can stay aerobic. But always pushing the pedals on the backstroke to give some limitation to my down-celeration, that will be new!
The mention of a "chainring pair" is disquieting. If you mean that you envision simply relocating the chain between larger and smaller chainrings during a given ride, it doesn't work that way. With anything more than a difference of only a very few chainring teeth, you'd have to shorten or lengthen the chain accordingly. That is, unless you play to swap sprockets on the rear wheel whenever you swap chainrings.
