Help! There is bullnose everywhere in this house and the customer wanted 22.5/22.5 cuts at the corners, but the baseboards are too thick for the door jams

If I preassemble/glue the corners that end at the door jam, it will be too thick for the doors to open/close. But if I beltsand the backside of the baseboard to better match the bullnose, the top edge of the baseboard will dive down with the contour of the sanding. They didn’t like the look of the shaped corners that match the bullnose, so I’m kinda stuck. What options are there?
