Any reason not to do this?
Your speed may be limited by wheel RPM. My Bafang mid-drive is, it has a magnet mounted to the rear wheel and a sensor on the chainstay. There is an easy hack that might work: mounting the magnet to the crank arm and moving the sensor. Still, with a 30t chainring I suspect that you would spin out if using e-assist.
What's your current top speed with throttle?
