As requested, here is an update, with the new config file, to match RepRap Firmware V3.0
Note: I completely removed the Z-axis endstop, and I am using Stall detection to home the Z axis.

Thanks Guyaros,
I was able to do the same conversion on my newer FFCP. Installed the Hemera and Duet Wifi and your configs worked very well. I ended up adding a BLTouch as well which has made homing the Z-axis more accurate plus adds all the benefits of bed levelling and mesh.
I remixed your Hemera mount to add a mount for the BLTouch and a 5cm post to tie the wiring to. Seems to work very well. I’ll post the remix on Thingiverse.
Thanks so much for your efforts. Much appreciated!

@Zebble any chance you can link to your remix? I'm getting ready to add a Hemera to my FFCP, and I'd like the option of BLtouch.

I wonder how feasible it would be to do a dual extruder version of this conversion. Is there a mirrored version of the Hemera?
