Using those bars will leave a large gap between torso/hip angles when using the hoods/drops and the tops. As pointed out, it can also lead to interference between the knees and bars when standing to climb or sprint. To overcome that, you WOULD need to change frame geometry.
Nothing comes without compromise.
Though looking at the OP posted photo, it appears you could just turn your hands and instead of gripping the tops, you could instead grip the sides anywhere along that long stretch of extension and thereby have your hands out front roughly the same amount as with conventional bars. The potential knee issue however wouldn't be solved.
