In short, you've provided the answer! The XSR will do it, certainly, but not in the comfort that a purpose built tourer would. Wind protection, seat comfort and suspension will all create issues on a long tour. If you intend to do a lot of touring, you'd be better off with a mid sized tourer instead - my choice, without hesitation, would be a DL650 VStrom. I've done single trips of 5+ hours in comfort on the XSR but I'd hesitate to take it on an epic multi day adventure. If it's a one-off trip and you want to enjoy all the other benefits of an XSR, then go for it! We'll look forward to your ride report!
