Nallath, Having just hacked my configuration files to add a Kossel Mini profile, it appears the only missing ingredient would be the ability to set a circular volume shape for the printer bound visualization. We did this before with the following configuration taken out of my old Cura 15.04 config (which doesn't function as written, I tried):
"machine_shape": {"default": "Circular"},
A circular build plate stl model, zero-centered coordinate system, and the flavor of gcode are already in the existing configuration files for other printers, and behave as I expect on my Kossel. So my expectation is this is a very simple thing to support.
