Marlin Diamond Hotend

Hey!
I have a Prusa i3 Hephestos and I will install the Diamond Hotend soon.
I have a question regarding the firmware.

At reprep.me they recommend "Marlin - The Diamond Hotend version" [github.com]

I actually use Marlin RC8 now. Is it possible to customize RC8 to the Diamond Hotend or did they change more than the config in the "Diamond Hotend version"? What do I have to change?

Thx!
