What are you expecting to save?
If your site is not running a specialty engine, adding one will help CPU performance since some of the DB2 work will be offloaded to the engine. Convincing your management that the savings is worth the $40,000 to $100,000 that the specialty engine costs, however, may be difficult.
Have you talked to your site support group about the query? They may have some suggestions for improvement, and they have more tools to investigate the query than we do.
