Even at the same ratio, this really depends on the ratio. If you're at the point where two motors just isn't enough power to accelerate quickly, you'll end up drawing more current (when averaged over time) total.
At speed with the same ratios and friction, your net current draw should be the same, you'll just be going slightly faster.
