You could set the option --ramps.guess (on initial import or for post-processing) and it will fix the geometry of the off-ramp so that it aligns better with the main road (less overlap). Note: - this will only work if the geometry of the off-ramp is not too dense (otherwise the adjacent geometry points will still look ugly) - the option will only trigger if the motorway is recognized as such which requires it to have a minimum speed of 79km/h (threshold adjustable with option --ramps.min-highway-speed)
Otherwise, your best remedy is to fix things manually in netedit: https://sumo.dlr.de/docs/Netedit/neteditUsageExamples.html#specifying_the_complete_geometry_of_an_edge_including_endpoints regards, Jakob Am Mi., 27.
