I'd say it's very likely that adding some kind of comp impact for filling those roles is going to create all manner of issues, and likely make the problem worse.  I'd suggest the issue here isn't that those roles are excluded - that's just a symptom.  Rather, the issue is with your comp system typing comp to achieving KPI's; that practice has all sorts of problems, and I'd say you'd do far better re-engineering your comp system to remove that aspect of it in the first place.  If you haven't already, consider reading Dan Pink's book Drive, which covers that practice in depth, and shares a lot science that suggests it's probably not a desirable practice.
