This is not possible with the supplied fetch schedulers so you need a customized scheduler. In Jira there's an open issue for support for different intervals depending on MIME-type, it is very similar to what you ask. It extends AdaptiveFetchSchedule and allows for setting different increment and decrement rates per MIME.
