[MCU] How powerful would someone become with the Super Soldier Serum (original) and the Heart-Shaped Herb combined in their body?

Not much more.  Both of them seem to enhance your physical abilities to a certain level (peak human), rather than increasing your abilities by a certain amount.  So strength, speed, endurance etc wouldn't really be cumulative across the two.

Any unique benefits you'd get from each aren't that significant- i think the herb gives more increased senses than the serum, but that's about it.
