Changing mullion profile in type

I’m trying to find a way to change the mullion profile incurtain wall types automatically.
For example, I have curtain wall types with A mullion profile as the Vertical Mullion Interior Type.
I want to change the A profile for all types to B profile or that there will not be a mullion profile at all in the interior type.
Can it be done?

Maybe, but first I would ask if you couldn’t just reload the new profile type into the old one via the project browser.

If the profile is used in multiple types, then this will not work.

To see if the parameter is available in Dynamo, you can use this nifty definition.

If it can’t be done with OTB Dynamo , then maybe with Python. But I can’t help you there.
