In principle yes. Either:

- add an artificial load by setting "job_load_adjustments"/"load_adjustment_decay_time" in a schedule to increase "np_load_avg"

- Use the least used host: http://wiki.gridengine.info/wiki/index.php/StephansBlog

But matching your original intention is only correctly mapped by the consumable. The other two ways may fail.
