Very limited alternatives, I'm afraid.
When my girlfriend bought her VT750 (2001, ACE) we asked for the light bar right away. Since the bike was not new il actually came with the Memphis Fats shield preinstalled and the shop attendant told us we couldn't fit one.
That was actually a couple of years back and we didn't (just yet) go thru with the project. We were offered a couple of solutions like using the flasher bar instead and adding new flashers afterwards or using C-clamp for new lights and since the bike still looks new with limited milleage on it, eventually I will look into it again.
Good luck
