Sorry but could I just point out that if you put a second lens to the right this would sit directly behind the front camera and the other Face ID tech in the dynamic island, which wouldn't fit. It is also where the logic board of the phone is. So that's a not starter.
The only way to do it would be to make the plateau larger vertically and add another camera below, but then you're starting to defeat the point of a thin phone. It also would be a significant redesign and I can't see Apple doing that after a year.
Personally I think we'll see a spec bump next September, or even just the current model receiving a price cut. Any redesign will be 2027 at the earliest , if they may just fold it into the redesigned iPhone 18.
