Sadly sir even though they may look like subtle design changes they are quite different from the original design so just swapping the parts is not really a option.
As for the fan ducts even the original design has a new fan duct model and swapping the filament during printing was always possible by using the pause option as the hot end remains at temperature and you can remove and load new filament.
Print settings in the Creatr Software can be directly updated in under 'print'.
