Does the other light have a photocell ?
I'd suggest putting the Air remote onto the hotshoe of a receiver from an alternative trigger system.
When I mix speedlights with my Safari, I stick the Safari trigger onto the hotshoe of a YN 622c, which I stick in my pocket, then I can control power of the speedlights from the camera hotshoe mounted 622tx and the Safari from the trigger in my pocket
Photocells aren't reliable with high ambient light levels.
What other strobes are you considering buying.
