WS10G is a new variant. I have just discovered this.

Not only is this very old and out of date, but it seems you've directly copy and pasted information from wikipedia, which is not very constructive.

Also, just because you've discovered information that is new to you, doesn't necessarily mean it is new to everyone else, so if you want to share something that you think may be new to other people, I recommend at least asking yourself whether it is actually going to be new or not.

Does anyone have any conceptual art on how a high bypass turbofan could fit in a stealth bomber? I struggle to picture how that would work while maintaining stealthy intakes and overall profile.

Higher bypass ratio doesn't always come with higher diameter of a engine. You can simply use 2 or more stages of fan to achieve high bypass ratio.

That's not what bypass ratio is, that's compression ratio. The bypass ratio is the volume of air channeled around the core divided by the volume channeled into the core. For a fixed core diameter, a higher bypass ratio by necessity entails a larger bypass channel which means a larger engine diameter.

By increasing the operating temperature you can shrink the core size.
You can also use a geared turbofan to increase bypass ratio.

The quad engine BAe146 aircraft had lower fuel consumption than other similar sized twin engine aircraft because it used geared turbofan engines while its competitors did not. The engines had a higher bypass ratio.
