I think you would have to angle the actual bulb as well (halides that are parallel to tank front right?) to get best results. That way direct light is focussed as well, not just the reflected.
However theorectically you will be fighting the inverse square law due to the extra distance travelled. I figure about a 20% loss for a 12" horizontal shift with a 24" bulb height and that doesn't take into account absorption by water.
IMO a more effective solution would be to mount the bulbs closer together and maintain a straight down focus. Though it may not be possible and the presence of a center brace could be an issue.
