I didn't do that, but I just did after first uninstalling wine and attempting to uninstall the i386 architecture. I got:
sudo dpkg --remove-architecture i386 [sudo] password for terry: dpkg: error: cannot remove architecture 'i386' currently in use by the database
Sounds like there are still i386 packages installed. But removing the architecture seems not needed, if you want to reinstall wine packages it should be sufficient to just uninstall the wine packages, but I am not sure what you are trying to accomplish with it.
