Help. Contemplating fitting a Brompton with the BMS Q85 83mm hub

I wonder if anyone 'out there' has done, or is contemplating doing the same? My main worry is whether spring the forks from their original 75mm to accept the 83mm would be sufficient.

The diameter of the hub at the point where it starts to taper off is approximately 80mm (extrapolated from the drawing) which means that around 40mm above the axle the fork might be a bit close to the motor.

Can anyone advise?

The alternative would be an 80mm hub from keyde

Has anyone fitted one of these? If so, does anyone know whether it is possible to fit a half-throttle rather than the speed regulator keyde supply?
