Snowflake DB Clone?

So this may be confusing but just looking to see if anyone has any insight on how to maybe do this in a simpler fashion. So our company utilizes Fivetran for data transport, Snowflake for warehousing and Tableau for BI. Unfortunately, we weren't able to get table or column descriptions from our On-prem into Snowflake; so all of our columns have system names (like FFDITM rather than Item_Number for instance). This obviously was not going to work so I created a new "Transformed" DB and manually added all columns with updated names. I am now in the process of creating streams to update the transformed DB on a daily basis but am running into many problems. I've done a bit of research and I do see that Snowflake does have a Cloning option for cloning our schemas and tables or even our full DB. If this is the case, can I clone our production DB once, then updated schema, table, and column names, and then finally set up streams to update it? That way its not so cumbersome? I attempted to manually do this all manually but it seems there are automated work arounds which will also not eat at our storage.
