This is great! The bane of dialog editors everywhere, and a great technique for patching those impossible-to-fill spots:
Such a brilliant way to take advantage of convolution reverb processing, which was already an amazing tool. I think I'm also going to dig out my copy of SoundHack and see if it's spectral shaping can be used to do the same type of thing, since I don't currently own a copy of TLSpace or Altiverb for ProTools. Though I do like to use Logic Pro's convolution reverb, Space Designer, perhaps I can create a bussing system in Logic to do the same thing, as this article suggests is possible.
