I don’t believe that will work but there’s no harm in trying.
However, have you tried using Orca Slicer and seeing if one of the Prusa profiles might work? You could load the printer definition that comes closest to the one you have. Then export the 3MF file and GCODE file separately and from there try to import into Prusa Slicer. It’s worth a shot.
Click on the little tab. It takes a few moments for it to build the list of printers and then type Prusa in the search
