You don't have to enable "use_materials" or make temperature serttings visible again or anything?

I tried doing this using only user-modifiable files (the .cfg files in the user's home, not the .json files inside the, usually cryptigraphically signed, .app MacOS application-package) but due to their limited syntax I could only get so far.
I guess I'll have to go your route to get the UM2extended to work with Octoprint.

Ultimaker/Cura#847 (comment)
aparently there is a secondary location outside the .app, so using JSON is now a viable option.

"use_materials" is new for Cura 2.2. Just setting the gcode flavor to anything not-UltiGcode is enough to make the material selection show up in 2.1. However I found out that properties such as printing temperature were being disabled by the UM2 definition.

I have updated the definition above to reenable these material properties. This should give you a printer that has all of the material-goodies of a non-UM2 printer.
