A friend of mine uses bullhorn bars and bar ends, that is on his Habenaro Titanium frame. I believe the frame that he has is a cyclocross frame. I am not sure where he found the carbon fork that has fittings for mounting panniers, but he got the fork separate from the frame.
He built up that bike for our 2014 Pacific Coast tour, still using it, the photo I posted is from our 2017 Southern Florida tour.
Since your reach on that type of bar will be much further forward than with conventional upright bars, that suggests that you want a frame with a shorter top tube. Thus you might have trouble finding a hybrid frame that will fit you well with that type of bar.
