Hopefully it will make a positive difference in the Wv9 for you
My main thought was that by stacking magnets on the corner feet you will increase the overall magnetic strength in the puzzle (in terms of adding stability) and since magnet strength decreases with distance, you should be able to loosen the screws to achieve better turning and feel without losing stability and controllablility
And my WRM 2019 is maglev

I bought a Ball-core RS3M Super extra and scaveged the BC and maglev from it to mod my WRM 2019

and then added corner magnet pieces from a Maru kit to the corner feet, and stacked 3×1mm N50's on the corner feet as well... it is sweeeet
I had thought to alao add 4×3mm N35's as repelling edge magnets but the edge feet would take a lot of finicky detail work to make that happen so I gave up on that part...
