One thing to watch out for in lifting the ground pin above ground on the 78xx series devices is that a momentary short of the output to ground can destroy the device, IOW the integral short circuit protection is effectively defeated. You'll also need to use insulating hardware if you want to heat sink the regulator by mounting it to the (grounded) chassis. The cleanest, easiest solution may simply be an LM317 set to 9.6 V output.
