Easy enough to do if you namespace the models. Just have a Model::DB class 
that does a Module::Pluggable search for MyModel::* and creates the classes on 
the fly by pushing stuff into their @ISA. Catalyst will pick this up fine - 
it's how Catalyst::Model::DBIC::Schema imports all the result classes (equiv. 
to CDBI table classes) into the Model namespace (well, it uses DBIC's 
compose_namespace function but the basic process is @ISA stuffing plus a 
little extra magic to make all the DBIC bits work together).
