(DC/Marvel) How would the Super Soldier Serum affect someone like Batman?

Would it just let him keep his peak physique without the need to train? Would it actually make him stronger? Bigger? It made Steve Rogers grow a couple of inches. Would Bruce go from 6'2 to 6'5?

Bruce Wayne is already an exceedingly excellent example of a human being. The SSS would make him a perfect one.

Yes it would make him much stronger. As to height? Effective human height with all the benefits of size and none of the downfalls of excessive height seems to be in the 6 foot to 6 1/2 foot range, so maybe Bruce gains an inch or three, but not much, and maybe none at all, being that his body is insanely efficient at the current height.

His musculature is perfectly tuned for his physiology, so likely the size of his muscles wouldn't grow, only the efficiency and power.

An SSS enhanced Bruce Wayne probably wouldn't actually look much different, he'd just pack a lot more power and ability into that same chiseled frame. Match that with his near human maximum combination of education and skill, and he'd be much more formidable than he already is.

He'd also be a different hero. Batman owns the night because the night gives him the edge over his opponents. Batman plans so well because he lacks the ability to go toe to toe with some of his opponents. He's so skilled to make up for his human limitations. He's so educated because he needs to know his opposition to plan against them.

If he could throw the perfect punch instead of having the perfect plan, do you think he'd spend so much of his life being good at planning, or punching? 

Batman is who he is mostly because of what he isn't. If you give him too much power, he doesn't need to be what he is any more.
