Personally, I don't believe it would fly, but of course that's just my opinion. I base this upon having played for decades, working every day of the week, and enjoying the light action of the PSR series and other brands. When I tried to fill in for a friend using his Clavinova at the end of the night my hands were so cramped from playing that hammered action board that I had to soak them in hot water for a couple hours while sipping margarattas and taking pain pills. I only filled in for him a few times, and the last time I did, I took my PSR-3000 to the job and hid it behind the Clav - No one knew but me.
Now, I am confident there will be posts to the contrary of mine, folks that really love playing the piano, though, instead of an arranger keyboard.
