NADP Accel Alts

Consider NADP1,

THR RED: 800'
ACCEL: 3000'

Is there any reason why I, due to operational reasons (e.g. constraints on SID) couldn't increase the ACCEL alt?

I have a hunch that the critical issue for NADP1 is close in noise sensitive areas which calls for a THR reduction early, followed by a decent gain in altitude before acceleration. It seems that perhaps 3000' has been chosen more as what the designers considered a minimum acceptable level rather than being specific. That is that they had to specify an alt and based on their research decided that 3000' was good for the procedure. Would my deciding to accelerate at 4000' or 5000' upset anyone?
