It shouldn't be big work to create a request bean that does the job of
setting session bean. The same way you set a property of request bean
from #{param.xxx} you can link the request bean to session bean by
setting a managed property in session bean to an EL pointing to session
bean (eg <value>#{someSessionBean}</value>). The most important part is
to ensure the request bean is used upon request by the view. This could
be done by calling a value of request bean.
