Paint the boom equipment green. Key it out, and rotoscope/garbage matte only what you can't key out.
Occasionally shoot some clean plates, if you think you need it.
But don't take my word for it, maybe test it with a painted green broom or stick. see how it goes. Maybe A green mic would cause other issues with refelections.
Camera and audio stores should sell green foam pop filters for most mic sizes.
I've seen all this done, but never did it myself.
Schoeps actually makes a chroma green version of the “Schoeps Blue”(CMIT 5) for keying work. If I was going to buy a “Blue”, I’d actually order the green version, because 1) I’ve never seen anyone with one in the wild and 2) I love green.
