DIY bottles exploding are mostly urban myth or lack of the one way valve.

Thats partially because when these things tank dump....the soda just tasts

I've been playing around (in my head) with the whole idea of using DIY
CO2
instead of presurized CO2 (cause of the cost and safety).

If I understand your idea, you believe that DIY CO2 suffers from control
problems, and you are proposing to store CO2 in a 4L "box", or soda
bottle to
solve that problem. I'm not sure that DIY CO2 actually has control
problems. I
think the issue is variable output over time, based on recipe, age of
mix,
ambient temperature, and other variables.

Consider this: if you use two DIY bottles, connect them with a T fitting
and
alternate renewing them, you will have a much more even output (change
the mix
of bottle A on day 0, bottle B on day 7, bottle A on day 14, etc.).
Next, if you
adjust your surface agitation, you can keep your CO2 concentration to
within 3-5
ppm pretty consistently.

BTW, you mention safety problems of pressurized CO2. I've heard many
more
stories about DIY exploding or dumping into tanks than I have of
pressurized
bottles causing problems. Millions of pressurized bottles are used in
soda
fountains worldwide, and you don't hear about many problems with those
either.
