HermitCrab CAN 2 heaters/thermistors

Hi,

I want to make a tool plate with two heaters and thermistors for:
https://www.thingiverse.com/thing:673816
or
https://shop.cultivate3d.com/product/medusa-multi-material-switching-system-for-2020-rails/

Is there any way to get the HermitCrab CAN to power and control a second heater?

Perhaps you could wire the heater and thermistor to the stepper pins outputs, and redefine the pins in the Klipper config file? Are there any sensitivity issues or hardware limitations that would prevent the thermistor from reading? I know you need a 4.7k pullup for most thermistors, could this be added in this case to the tool plate board?

Could you add a pdf that specifies the Amps you can put through each pin on the tool plate?

Thanks!
