Though, something to watch out for is ground loops. Counterintuitively, adding more engine grounds (rather than, say, swapping the existing ground wires out for bigger ones) can cause all manner of odd behavior in sensitive modern electronics.
I work in the low voltage field and landing both sides of an electrical drain can prevent sensors from working entirely. I can't count the number of times I've had to cut grounds technicians placed at both ends. If the ground paths are properly engineered to begin with (a big if), I'd be wary of changing the number.
