Sorry, but with the diamond I see the width of three seats instead of two.
I presume you were concerned about the rounded shape of the top hitting the heads in the direction ol lenght of vehicle's body.

But this configuration creats needs to expand the width of the vehicle, and maybe alter dra coefficient.

The pant of the wheel it's connected to the vehicle's body. Unless it get like APtera front wheel. If you cut it, it would not possible to it to turn, since it would face the car's body as a barrier .

Loads of leg- and elbow-room.

My preferred solution for full wheel pants would be a secondary steering arm that would turn the pant half as much as the wheel.

"Tail-guner' is a colloquialism for the 3rd rear-facing seat in a station wagon.
