I can think of an alternate setup
T32 in flash shoe with head pointing up toward ceiling
T-cord leading out of T32 to multi-connector to one or two T20s
T20s pointed at walls and/or ceiling, no other diffusers
Quick and simple to set up. Walls may add a color cast but that might
be overcome with proper white balance setting. But setup needs to be
repeatable to save rebalancing light and color.
