If air is good, can Ozone be better?

I cobbled up a small Corona-type Ozone Generator, and am pumping Ozone into my etching solution, rather than plain air. It would seem to me that that could be even better than straight Oxygen. Unfortunately (for testing purposes), my etchant really does not require regeneration at this time, so I can't compare the results.

Perhaps Mr Seychell could add some light. I looked at his equation 4 from his excellent site

[4] 2HCl {aq} + 2CuCl {aq} + O {aq} → 2CuCl2 {aq} + H2O{aq}

and wonder what the result using Ozone would be ?

I realize Ozone is highly reactive, and might affect my cheap air pump, as well as do something to the tubing - over time -
Also wonder if any ill effects might result from this - reacting differently to the HCl perhaps . . .

As you all can probably tell, I seem to have entirely too much time on my hands - but when your retired it is no problem.
Just "thinking outside the box" again.

Any comments?
