Yes, we have used it to do the exact same thing. And it works without issues. We pass all the values even if its just a port change.
restore_host_config -reconf_db [-host <new db host
name>] [-port <new db port number>]
[-dbname <new db schema name>] [-service <new db service
name>] [-owner <new db owner name>] [[-password <dbo password>]
