Can the Paletta, Selador Series be used to light a green screen infinity wall?

We have 8 Paletta's attached to a lighting rig via pantographs which were installed primarily as cyc lights to use on the permanent green infinity wall that is curved into the floor and which is aprox 6 x 6 metres. The Palettas are rigged at aprox I metre from the wall. We have a range of H40 - V90 diffusers but have not been able to use these lights to fill the space with a balanced wash and have continuous hot spot issues which are not ideal at all. Can you please advise?
