LARAVEL add custom method Illuminate\Cache\RedisStore

I want to extend Illuminate\Cache\RedisStore class to add a custom method where i can use JSON_encode instead of PHP Serializer before sending the data to cache servers.

I tried extending both the Redis and Cache Facades then registering the alias in App.php to load the extended facade on bootstrapping.But getting the error RedisStore doesn't implement this method.
