How to Convert Text TYPES to Other Existing Text TYPES?

I currently have imported a lot of text types through an Excel add-in, and I need to consolidate this list and convert these imported types to existing types.

I want to make all of these imported text types become another existing text type (as this will have to be done every time someone uses the Excel import add-in). Based on what I’ve seen on the forum so far, it seems most posts are changing the selected font within the named type, whereas I need to convert an entire type to another type (Ex: Imported_2.45mm Arial Narrow needs to be converted into an existing 3/32" Arial Text type)

“Text Font” doesn’t change the actual text type, and I get an error with most other parameters I’ve tried…

Is this possible?

Something similar to here, but is there a node for dropdown menu of text types somewhere?
