I had a chance to start putting my car together this weekend. There are some issues but basically, this looks to me like an attractive and viable option for a more robust open-wheel class. For those who do not want to go this way, we can run both the current F1 and this new GP Formula classes (separately, of course).
Here are some pics:

With wheels on. Rear tyres are AllSlotCar, fronts are older F1s (I forgot to order the AllSlotCar front tyres).

This is one with the original AllSlotCar plastic chassis, but you can see where the chip will go.

I'm proposing the following rules for the class:
Class Name: GP Formula
For AllSlotCar GP Formula cars with the following specifications:
• Body: AllSlotCar body (must be painted - no unpainted bodies allowed. We want this class to have cars that look like real F1 cars).
• Chassis: Sloting Plus GP Formula aluminium chassis.
• Interior: At least shelf and driver head required. Must comply with General item 3.
• Digital Chip: Free.
• Motor: All Slot Car 22K motor (Part No AS001). We can instead allow any FK130 up to 22,000 RPM.
• Gearing: Free.
• Magnets: USD rule.
• Wheels: All Slot Car front and rear GP aluminum evo wheels. We can allow alternative wheels however they must be of F1 dimensions.
• Axles: Free.
• Tyres: All Slot Car GP front and rear tyres. We can allow alternative tyres however they must be of F1 dimensions.
• Guide Flag: Free.
These are suggestions which we can refine after doing some tests.
