Sun T4 server with Dynamic threading, can database listener be used to pass single-thread-CPU priori

We will be migrating to a Sun T4 server, which has dynamic CPU threading and have an Oracle 11.2.0.3 database.  It has a couple of processes that connect every 10 minutes and use high-cpu.  They must complete in this interval.
 I want to give them single-thread CPU priority, in a similar way to the way the logwriter is given this priority in Doc 1523164.1.  However, a new connection, and process number, is created at every connection.

Can I create a second listener and use priocntl to give that listener this higher priority, and then it would fork this priority on to only the processes that connect through it?
