I'd say my conclusion was opposite! I've seen something like a 33-40% reduction in fuel economy, both in average and peak, compared with the stock engine.

Here's an example:

At 60mph, in 6th gear, my engine turns almost exactly 2000rpm. If I'm rolling down a hill at a constant 60mph, I can shift to neutral, then hold the revs @ 2000rpm, and my fuel economy is only ~65-70mpg.

Meanwhile, with the stock engine, I was able to see maybe 85mpg cruising @ 60mph on level ground. At 50mph, my fuel economy could reach or exceed 100mpg.
Did you ever get a chance to run the stock engine with the electric drive disabled? You must compare apples to apples. The hybrid drive allows the 3-cylinder to avoid its most inefficient operating points.

I drew my initial conclusion looking at the lifetime mpg figures you posted for both cars, btw.

A hybrid drive with your current setup should allow you to do the similar to the original, but I imagine remapping the ECU to take advantage of the larger engine's different operating characteristics would be a total nightmare, nevermind everything else you'd have to do to make it all work.

Soon, all that may be available in the U.S. are crossover blobs and oversized trucks. And then if/when the fad dies, they'll be scrambling for a taxpayer funded bailout as masses of vehicles sit unsold...
