fire off multiple dbms_stats.gather_schema

I am using dynamic sql to generate code that will analyze schemas. I would just gather_database stats, but the request is that I use dbms_stats.gather_Schema so that the process can be broken down into concurrent sets and run concurrently(and with parallel). Does anyone have any advice, ideas or tips on how I might accomplish this?

Here is what I'm currently using:
select
'exec dbms_stats.gather_schema_stats(ownname=> ' ||chr(39)||
owner||chr(39)||' ,estimate_percent=> 10 ,cascade=> TRUE , block_sample=> TRUE ,degree=> 4);'
 FROM DBA_TABLES
  WHERE OWNER NOT IN ('SYS')
  AND PARTITIONED = 'NO'
  AND LAST_ANALYZED < SYSDATE - 14
UNION
select
'exec dbms_stats.gather_schema_stats(ownname=> ' ||chr(39)||
owner||chr(39)||' , estimate_percent=> 10 ,cascade=> TRUE , block_sample=> TRUE ,degree=> 4);'
 FROM DBA_TABLES
  WHERE OWNER NOT IN ('SYS')
  AND LAST_ANALYZED IS NULL; Yes, I do know that the options clause will take care of some of the functionality that I am filtering via the predicate and I have plans to incorporate that feature.
Thanks!
