Wondering about the possibility of a modification to the register switch selection on an LMMH. This model has 8 switches (non-master) and I've seen variations of the same model with Musette (MMH, imitation) while others have Harmonium (LMH) in the same place on the register switch bank. Is it possible to alter the reed switches' function to select an imitation musette instead of selecting one of the current 8 combinations? What might that cost or what would be involved to modify? (I thought it might be just filiing out a hole and covering an existing hole in the plate. Finding a matching musette switch to reflect this is limited to scrapping an old one for parts, or do people repaint them? Not sure if its an embedded plastic or painted switch. Thanks for any info you can offer.
