I gather the idea is you are looking for a system that will work for more
than a couple of weeks without human intervention ..... a problem I can see
with your system is that as the level of the sugar water drops the time the
air pump will be required to run to effect the correct dose of feed for the
yeast factory will have to be increased. Also the amount would be different
(more) each time, and difficult to calculate without a human there to say
enough.
I have just read this post and it sounds like I set out to be negative. I'm
don't mean to be at all. I like these "tell me why this won't work" sort of
questions and I'm just giving my opinion.

free
to tell me why this wouldn't work.

* digital timer periodically turns on air pump, forcing air into sugar
water
chamber and moving fresh sugar water into the yeast factory
* air injection must be valved, since most timers run for at least 60
seconds, which would inject too much air if left full-throttle
* when fluid level in factory rises, alcohol on surface overflows into
waste
chamber
* co2 production remains more level than DIY 2-liter bottle systems
* maintenence consists of topping up with sugar water and emptying waste
chamber.
* vessels larger than 2-liters can be used to extend maintenance time,
without co2 drowning in its own waste and dying off
* higher concentrations of sugar coupled with smaller injections can
further
extend maintenance time, at the cost of more co2 fluctuations
* co2 production can be tuned by altering air pump cycles with the digital
timer, and by varying the surgar content of the supply
