Double Flash Set-up... What do you think?

Calling all pro's... what do you think of my set-up.... it's untested so i'm looking for comments - do you think it will work?.... Set-up is for weddings using a NIkon D1, Quantum Qflash with TUrbo Battery and a SB-80dx with a Quantum battery 1+... In landscape position, the quantum will be used as a bounce flash pointed at the ceiling with the SB-80dx used as a fill... In portraite position the roles will then be exchanged as seen in the pics... The system works great in my small white walled apartment but then again any type of bounce flash looks great in here... : )
