The CLR does support loading multiple versions of strongly named assemblies into the same AppDomain. This only works though if your assemblies are strongly named and each one has a different version than the other.

I'm guessing it's more likely that you are dealing with unsigned assemblies. If that is the case then what you're asking for isn't really possible. Once a given assembly is loaded into an AppDomain it will remain there until the AppDomain is unloaded. To get this to work you will have to abstract out all of the work around the loaded assemblies into a separate AppDomain and use a new AppDomain for every assembly
