We're not talking about total turbo potential, we're talking about two turbos on the same engine, both capable of making a given pressure at a given flow rate (CFM).

That is not possible unless we're talking about IDENTICAL turbos here.
(And even with two same turbo models, there is still miniscule differences in efficiency cause of production machining tolerances.)
AFAIK, there is no such thing as two different turbo models flowing exactly the same specs - do you have proof of such beasts?

Flow and pressure are directly related;

That only holds true if we narrow our conversation to a single turbo.
You cannot say that when talking about different turbos - which we are.

So where does the power come from when you swap to a larger cold side? Increased efficiency, and thus a cooler air charge.

I think you're overemphasizing air temps.
By nature, PV=nRT comes into play, and you're just stating the obvious.
