Which is exactly what a solo fight should contain more of! That's what I like to see, and what I failed to see for so long near the end of 3.x due to PC power escalation.
Back to topic: I just remembered all the Quest info in Barakus, especially the subplots and minor dungeons in and around Endhome. These are setup almost exactly like 4e's Quests are, and it'd be a snap to convert this info over.
And maybe I'm just weird, but there's a decent number of watery encounters found throughout the book, and I think 4e handles water monsters better (i.e. makes them feel more "unique").
