This seems a bit silly to ask, but I started on organ many years ago, and became accustomed to L&R sounds when I switched to arrangers. I have many arrangements on my SD40 with almost non-existent left sounds, which I would have to make if using my controller instead of my SK1.

The question is whether it is worth the work, as I see arrangers played all the time with LH used for chords for the arranger only. I normally use LH sounds to add to accomp and transition fills etc, but don't have to.
