I think I see where you're coming from. And I can kind of agree with your statement of the 2AZ engine would not be that different with a GE head, so I'll do put what I'm thinking a different way. This is going to be similar in comparison to the late ZZ series simply because it's the easiest way for me to explain.
Lets say hypothetically Toyota designed an engine called the XAZ-GE:
4 cylinder, 90.5mm bore, 92mm stroke = 2367cc or 2.4L slightly under-square.
I worked with some calculations and simply put; this engine hypothetically is capable of more than 200bhp @7000rpm naturally aspirated.
This is the type of engine that the G head was designed to be put on. But another bit I must add is that while the G "indicates" a wide angle valve head there is much more to the engine than the little letter indicates...
Please have a look at the following technical PDF on the 2ZZ-GE to see what I'm trying to explain. There are similarities to the 1ZZ-FE and 1ZZ-FED, but there are also many differences in components and materials for the pursuit of reliable performance, hence why it was expensive to manufacture.

Hope this clears some misinterpretation.
