A Jhook and some keck clips will really complete that. Sorry if that's what you were thinking already, but that will give you a bunch of options. I love modular setups like the one you picked because you can always choose the amount of diffusion you want. You can also play with them with other setups, it's a lot of fun. Funny thing, for the longest time, I didn't get a Jhook and used it upside down.
