RQS support dynamic limits. But for now only for host based rules; and in addition there is no complex variable like "total_slots" which is adjusted automatically. So, the answer it: no.

Nevertheless you could use some external cron script, which will generate the appropriate RQS on-the-fly and feeds it into SGE.
