Arduino throttle into bosch middrive

Hey guys,
I sold my stealth years ago and just started getting back into ebikes post covid, I have a cube stereo 160 on order but one thing i noticed on the demo was uphill technical rock climbs meant I was scraping crank arms, so...

i was wondering if anyone has came up with a way to add a throttle to a bosch CX PAS system?

I was thinking with an arduino or something you could mimic the cadience and torque sensor going in to essentially create a throttle input, anyone attempted something similar?

Thanks in advance!
