[Mauiusers] job preemption - can this be done?

Running maui/torque on a number of clusters. Have never used the
preemtion stuff before but upon searching through the documentation what
I'd like to do might not be able to be done here.
I'd like 4 classes/queues. A preempts B prempts C and D preempts C.
C is the general purpose totally premptable class. Both D and B can get
their bits they need by preempting jobs in this class. And I believe
that this would be all fine and good except for this A class which needs
full access to the machine (less D class jobs) NOW!
I've looked through the Maui docs as well as the moab ones to no avail.
Preliminary searching leads me to SGE and LSF. But it sure would be
nice to make this something maui could handle.
Anyone know of a way or something I may be missing? I guess I could
kill jobs out of a prologue script for A class jobs until I freed enough
cores. I don't know.
