Hope springs eternal.
Realize the constant slight offset of any amount and/or any imbalance of the cover will only worsen over time/rotations the offset and will likely lead to CF cover's self-destruction and/or separation.
The lightweight aspect is in your favor.
But my concern here is say the shock loading of say hitting a pothole shifting the cover any amount and when driven at speed that imbalance will only increase as the cover moves more off center.
I would not drive the car at speed in this condition with your arm resting on the open windowsill.
