Is it possible to change the HDRI backplate file, over time in Movie Render Queue?

Is it possible to change the HDRI backplate file, over time in Movie Render Queue?
I am trying to make a sequence of cameras that use different HDRI files and positions, but when i program the skylight (cubemap), it wont change the cubemap on the render, just the lightining.
Is it possible to achieve that?
Thanks a lot
