If you were to scuf all 8 face buttons, you could have a chorded keyboard with 255 non zero patterns without ever moving your hands if you manage to put one together for your hand size. I haven’t tried @Pat.Chet.02 's yet (Unofficial) V5 Controller Ergonomic Upgrade Kit, 8 Paddle Scuf, USB-C, Belt-clip Holster, etc - #6 by Pat.Chet.02
Folk with fewer fingers will have plenty of volunteers interested in modifying an average scuf design.
