It would contribute to making the CPU containing this circuit not horrendously huge/slow. By a little bit.
Also, does anyone else think that a hex subtractor could be faster/smaller than the hex adder?
I don't think so. Binary ones have the advantage of being able to use instant logic, so the fastest possible speed is theoretically 0 ticks. Hex ones necessarily always go through at least 2 comparators.
Posting when just waking up is a bad idea.
Let's try that again!
Uhm, isn't a subtractor pretty much the same thing as an adder anyway?

Almost. Since comparators are already able to subtract, subtraction would theoretically take only one gate delay, as opposed to three gate delays since addition requires one comparator to invert and one to invert back. Modifying a hex adder to subtract would add yet another gate delay from inversion.
