The Riv looks to me like a case of BD but not HU. In my experience, moving the hoods further up on Nitto Noodles makes for a weird ramps/hoods transition and the levers move further away from the drops forcing your wrists in an uncomfy position.
My experience is that these levers are always uncomfortable compared to modern ones...
The bars look okay to me, drops pointing to the rear brake bridge. The hoods could actually come down a bit.
