If you are willing to switch to a Zee, or Saint, brake the hose is connected at the caliper via a banjo-style connector, which allows for usually about 270deg. of motion around the axis of the fixing bolt. Many brakes use this kind of connector, but on Saint and Zee models, the fixing bolt is parallel to the caliper mounting bolts and pads, allowing the hose to be positioned at a 90deg. angle from the caliper, as seen from above. I'm not sure which direction you want the hose to point, but other brakes have the fixing bolt in other orientations. SLX and XT have it perpendicular to the previously mentioned models, so the hose pivots parallel to the pads. Tektro/TRP, Sram, Formula, and Hope all make brakes with banjo fittings. Check photos of the calipers, there's definitely something out there that cant point the direction you want!
