I imagine it's that combo of salty, savory, and sweet that draws you in.

But from the description I found online, it's way too much of each part to even seem like a good idea.

I could see those elements on toast though... You get the crunch of the toast and the bacon, that would handle the texture aspect.

Then just having a spread of peanut butter and jam instead of full jars would complement the savory of the bacon better.

The description of the loaf specifies grape jelly... I'd swap that out for something like a marmalade for some more acid to balance things out.
