Just to add my bit I've put can to cam links on one of my bikes, by using the standard can end bolts and drilling and tapping them to fit the standard m10 banjo bolt, then cutting and re-tapping the thread of a m10 banjo bolt to the m8 size on the can cover side hole. I then used the standard size brake line hose.
A local machine shop could do this for you for not a lot of cash.
