Oh, I don't know that it can't work.  In any case, you've opened up
a few ideas which should be explored.  

Normally, humans are quite sensitive to Ozone (.01 PPM), and, in 
some, quite small quantities can cause quite violent headaches, 
(.1-1 PPM), lung irritation, etc.  So, it doesn't take a lot of 
Ozone to cause some problems (OSHA PEL of .1 PPM, NIOSH IDLH limit 
of 5 PPM.).

Additionally, the process of producing Ozone may also produce other
highly reactive materials when using air as the starting source.
Various Oxides of Nitrogen may also be produced, some of which have
some strange effects (laughing gas, toxicity, etc.).  So, some care
needs to be exercised in Ozone production.

The question really becomes whether the Ozone will penetrate the
water and react with the Copper compounds (which I can't/won't
answer here).

But, thinking about this a little farther makes one wonder if there
are conditions for pushing more Oxygen into the water.  The
solubility of most gases in water increases at lower temperatures.
Thus, chilling the solution might increase the Oxygenation of it.
On the other hand, chilling also tends to slow down chemical 
reactions, too, so anyone running the equations would have to factor
this in (Or, maybe it would be easier to do it empirically?).

Would increasing the pressure the solution is under lead to more
concentration of Oxygen in the solution (Ack!  Don't rupture the 
container and spray the stuff all over the place, though.)?

Are there any catalysts which could speed up the reaction?

Yeah, I'm a lurker, too, but sometimes it's good to speak up when
your brain gets stimulated.  :-)

Now, if I only had the time to actually try some of these things.
