In case someone is interested, the following hacky filter worked at first glance.

#!/usr/local/bin/python3

"""

Pandoc filter to convert code blocks of certain language classes to code class

"""

from pandocfilters import *

def addCodeClass(key, value, format, meta):

if key == 'CodeBlock':

[[ident, classes, keyvals], code] = value

if "python" in classes:

classes.remove("python")

classes.append("code")

return CodeBlock([ident, classes, keyvals], code)

if __name__ == "__main__":

toJSONFilter(addCodeClass)

You could use a filter to add the "code" class to, say,
all code blocks with the "python" class.
