Can you IR special mic setups?

(Disclaimer: I'm noob about IR, and I don't have the equipment to do it.)

My favorite guitarist, Trey from Morbid Angel used a few very weird micing technique, which no one used as far as I can know. For example puting a metal mixing bowl around the mic, place the mic in to a glass bowl, or placing a fan between the mic and the cab.

My question is: if I do an IR with the micing described above, can I replicate this sound on a normal guitar tone?

I'm not sure about that specific technique, but you should theoretically be able to create an IR out of literally any system that allows you to pass a signal completely through it.

So yeah, any IR creation tool should be able to do that. As long as it can send out a signal and listen back to whatever the mic connected to it eventually hears, you can do whatever you want in between.

I will say though, that putting something like a desk fan in the equation might not get you the results you're looking for. IR's basically create a filter of a very, very small moment in time. I'm not sure if you'd be able to replicate something that happens over a relatively "long" time like fan blades continuously running between the cab and the mic.

An IR will be able to better represent mic'ing situations that don't change. Putting a mic in a bowl and recording that is fine because it's always going to record the same basic EQ signature over time. But a fan blade constantly appearing and disappearing between the mic and speaker is not something IR tech can easily replicate.
