Below is what I have so far. I would like to have a neater way of changing char to varchar2, and I would like to change the table names to tablename_int.

select 'select replace(dbms_metadata.get_ddl(object_type=>'||''''||'TABLE'||''''||',name=>'||''''||table_name||''''||',schema=>'|| ''''||owner||''''||')'||'||'||''''||';'||''''|| ','||''''||'CHAR('||''''||','||''''||'varchar2('||''''||') from dual;' from dba_tables where owner='SCOTT';

I need to change all the char data types to varchar2. Is there any way to set a transformation in dbms_metadata to do that transformation as the DDL is generated for the interim table?
