Ambitious. The software isn't designed for this but you might be able to slice twice and manually combine the gcode. Settings for the second slice would be:
Custom STL with the profiles offset in X and Y (adding material) by half the diameter of your cutter
No-extrusion gcode style
One perimeter, 0% infill
Microscopic but nonzero external perimeter extrusion width (Zero would set it to automatic)
You might have to add a G1 to some specific X and Y coordinates that put the cutter on the same side of the part as the perimeter start so the travel move at the beginning doesn't cross the part.
