Two 1/8" kerf ATBR blades stacked side-by-side (with a little shim to make up for the difference in the plate thickness from the carbide tips) would do what you want to do without the tell-tale "ears" that virtualy all the quality dado sets give you. (the very tip of the outer blades are set up to score for clean cross-cutting)
The router table is anothe option, but I'd worry about tear-out...for the figured stuff you are using, I wouldn't do this without backer blocks both in front of and in the back of the actual stock.
