Why not get the Blackbird and spend the difference between that and a ZX1000SX on something completely different?
Whats the range like on an SV1000? You can get side boxes and a top box for them, change the bars and screen and could good?
Aprilia Futura? Another litre V-twin worth a look.
What about a Triumph Tiger 1050? Lovely, lovely engine, can take panniers and top box, handles very well with it's proper road tyres, commanding riding position, comfortable.

What's your budget? A Multistrada might fit the bill?
Triumph Sprint is another dull bike to be honest. Essentially you're after the holy grail - an exciting bike that is still practical and comfortable! Personally, if you want an IL4 engine I'd go for the Kawasaki Z1000SX
Budget can be around 10k for the bike alone. What's the multi strata like for long journeys?
Actually the more I look at it the more I like the Z1000SX, I might even go for a test ride myself.
