This is not difficult.
You have M mount lenses that you like to use; you prefer the DoF from full frame; you like using RFs; you don't have time for film; you don't want to lug a large camera around.
There is only one camera that fits the bill - the M9. You can afford it, so just do it and start enjoying your recreational photography again. I look forward to seeing images from your m9 in the near future
