Recreate multi shader with Xpresso/Mograph?

[renderingz]

I'm trying to iterate through a set number of textures per a set numbers of clone. I think I read somewhere before someone had a solution using the time effector and offsetting animation of a texture, but I can't find the thread, alternatively it might be possible to do with Xpresso, and iterating through a hierarchy? Any ideas or setups for this from anyone who's achieved it would be greatly appreciated.

Thank you!
