The wall thickness is 1,2mm but the lip is only 0,6mm thick. How will the 0,4mm nozzle solve this?
Alternatively I could choose a 0,8 mm thick lip, but then the connecting end should be 0,4mm that is too thin.

I'd say you should experiment with Slic3r
it can manage extrusion in very sophisticated way
it can overextrude if you need a line wider than actual nozzle size as same as it can underextrude if needed it can even change extrusion continuously while extruding one line
i use mattercontrol
take a look here - this is the same object the same layer and the same settings
please notice - this object has wall thicknes exactly 2 times nozzle diam
here is what i get with
