AFAIK, it is not feasible.

eg:
When the config-property of ManagedConnectionFactory is updated,
application server can check whether the config-property
supportsDynamicUpdates. If it supports, instead
of re-configuring the connection pool, the MCF bean would be updated.

Not yet available in GlassFish.

For the Resource Adapter Java Bean, you can create
resource-adapter-config
http://download.oracle.com/docs/cd/E18930_01/html/821-2433/create-resource-adapter-config-1.html
using which you can override the bean's properties. When you update the
resource-adapter-config, RAR will be re-configured.
