While Duc service intervals have gotten better, I'd go with a Japanese bike. Plenty to choose from. Especially with the mileage you plan to pack on - I've put about 15k on my 919 this year, which would be 2 Ducati service intervals.
If you want new...CB1000R, FZ8, FZ1, SV, Z1000, Ninja 1000...maybe even a Triple.
My 919 is by far the cheapest to maintain, and I can still rip in the mountains, and do 500 mile days.

We've started a family, and I'm trying to squeeze rides (long rides are probably out) - so I'm going to try to just commute on the 919 now. I'm keeping the R6 for the track, however.
