It's much more complicated than that - you can edit the scheduling class dispatch table, which includes the time slice for each priority level and the bits that control what priority level processes go to when they are put back into the queues. This is done with dispadmin, but I wouldn't recommend doing it without learning a whole lot about how the Solaris scheduler works, via a kernel/tuning class or book.
