Let's get this out of the way first: I know that SessionFactory is immutable - I'm trying to change the Configuration at runtime and regenerate ISessionFactory.

Specifically, I have a Customer mapped that will have some fields added to its dynamic-component node at runtime. I would like to do something like this

var newSessionFactory = previousConfiguration
  .RemoveClassMapping(typeof(Customer))
  .AddXmlString(newMappingForCustomer)
  .BuildSessionFactory();

However, I don't see any obvious way to remove a mapping, is there anything I can do short of regenerating the entire Configuration?
