Sure, but wait a minute.  The interesting thing about Lombardi's plots were the selection of content and organization that revealed visual pattern in the edges, not their curvaceousness.

I guess the question is could we formulate networks problems so well that we can learn (train) pattern from one human-produced layout and apply (score) another set of network data.

I believe the answer is "not now"

We could have pseudo-Lombardi edges--curved in some fashion rather than dead straight.
