With a proper exhaust and you add a TWIN turbo you (not single) you will hear a lot less harshness in the engine. It won't go away, but it will reduce.

how will that help internally balance an inherently unbalanced engine design?

Not really sure how that will help, though. Like Dan is saying, unless you're building (and balancing) motor internals, I don't see how just forcing more air through it is going to make it feel any smoother. Power delivery will feel smoother, yes, but the engine itself should still feel pretty much the same at high RPMs.

Now, with the added rush of another 100+ whp, you probably won't be focused on that at all. It could just be a psychological effect.
