to tell me why this wouldn't work.

My gut tells me that it wouldn't work, but it won't explain to me why.
It can be petulant like that.

So long as the system was pressure sealed (specifically where the
alcohol run-off is) so that produced CO2 actually goes where you want
it, I can't see any problem.

In addition to your 'splitter' valve after the air pump to ensure that
not too much air gets pumped in, you may want to consider a check
valve to make sure that air can only go into the system there, and not
come back out. Will check valves stop air, or do they only work with
liquids?

I wonder if a micro-pump could be used instead of the air pump, such
that it moved water directly from the sugar water reservoir into the
yeast factory? I'm sure some sort of 'dosing' pump like that must
exist, but it probably is for medical purposes, and priced accordingly
high, whereas your approach is very cheap.

I think you should build it and let us know how it goes
