As strange as it may sound, probably every state North/South/Border had some unit(s) with Zouave connections either in name/organization/dress. It seemed to have been the fashionable thing to do at the time. About the most complete listing of Zouave units that I have found is at www.zouavedatabase.weebly.com/civil-war-zouave-unit-master-list.html
There were at least eleven other Zouave units in both armies that had some connections to or used Fire Zouaves in their titles. Whenever I took a group of firefighters from the National Fire Academy on a tour of Gettysburg, they always laughed when I pointed out that the firefighter and the soldier on this statue are holding hands...all except the firefighters from the FDNY who didn't seem to be quite so amused.
Company H "South Carolina Zouave Volunteers" of Hampton's Legion went up against the 5th New York "Duryee's Zouaves" at Second Manassas. That was when the 5th New York was absolutely decimated by the Texas Brigade, which included the infantry battalion of Hampton's Legion at the time.
Company H joined the legion not long before the battle and that was their first combat. It largely consisted of men from the disbanded state militia unit, the Charleston Zouave Cadets.

After everything that has been said in this discussion, I now find it hard to imagine a time when they would NOT have confronted each other across the battlefield! I had no idea there were so may Zouave units on either side!
Read somewhere years ago, one reason for choosing the Zouave uniform was practicality? Not that they seem all that practical to wear, it was procuring- when units were forming in 1861, government uniforms were not yet available ( ? is that true? ), much less the whole blue/gray thing decided on. Women sewed what local regiments wore. Apparently the Zouave uniform was just easier to make?
Besides the ' dash ', you can see where it would be the case where they were easier/quicker.
