Need suggestions with massive query

Question

I have a huge report that gathers data about all facets of the company to display in one place. I have built a procedure to calculate and store the data (as it gets processed once and viewed often), but the query to display it is huge - about 1950 lines or 104 KB. I can run the report fine in SQL developer, but I need it in APEX, which is limited in its report area to 32KB per query. The report is basically the same chunk over and over referencing each of the saved calculations in a particular order. Here's a sample of a report section:
union
select 833 as SCTN_ID, 'Efficiency' as SCTN
     , 'Variance' as TTL
     , (select to_char(GOAL-ACTUAL) from vf_run_byweek_dtl a
         where a.run_id = p.run_id and a.section = 'HARD_BRAKES'
           and a.period_start = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')-6) as WK1
     , (select to_char(GOAL-ACTUAL) from vf_run_byweek_dtl a
         where a.run_id = p.run_id and a.section = 'HARD_BRAKES'
           and a.period_start = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')-13) as WK2
     , (select to_char(GOAL-ACTUAL) from vf_run_byweek_dtl a
         where a.run_id = p.run_id and a.section = 'HARD_BRAKES'
           and a.period_start = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')-20) as WK3
     , (select to_char(GOAL-ACTUAL) from vf_run_byweek_dtl a
         where a.run_id = p.run_id and a.section = 'HARD_BRAKES'
           and a.period_start = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')-27) as WK4
     , (select to_char(GOAL-ACTUAL) from vf_run_byweek_dtl a
         where a.run_id = p.run_id and a.section = 'HARD_BRAKES'
           and a.period_start = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')-34) as WK5
     , 'var' as CLASS
  from vf_run_byweek p
where p.org_id = :P2007_ORG_ID
   and p.last_day = to_date(:P2007_LAST_DAY,'MM/DD/YYYY')
...There are about 20 report areas - not all the same format - and each area usually has the target, actual, variance, and variance as % displayed for 5 weeks at a time on a rolling basis - so a 5x9 grid for each area once you add in variable column headers, etc. The sample above gives me one line of the 5 or so in a section.
I need some way to get around the 32K limit. I've tried building this as a view, but I need to pass in the parameters to select the correct date and organization. Can someone suggest a solution? (PS, I am trying to stay away from a stored procedure if possible as a standard report format will download to csv.)
