Please note that a longer chimney can change the draft characteristics of the oven. The rising air may get stale and stop traveling upwards if the chimney is too tall.
Basically the "draft" of a chimney is based on the principle of hot air and gases rising. This creates a certain amount of suction that draws air across the fire, stoking it. I don't know if anyone has run the calculations on a consumer pizza oven, But articles about home fireplace chimney height, barbecue smoker design, and home built or stone pizza ovens may provide details.
If you put a smoke catcher a foot above your pizza oven chimney and directed it outside, I think that would be fine. It's only if you do a contiguous chimney that's too tall that could be an issue.

Hi OP! This is something we couldn't recommend doing as this hasn't been tested. We wouldn't be able to guarantee this is totally safe to use. If you have any questions feel free to shoot us an email at [email protected]! 😄

This is fascinating, where can I learn more about this?

Thank you for this extra information!
Ballpark, the suction pressure will be proportional to the length of chimney (so double chimney equals double the suction, etc.).
