I'm not sure what you mean by "dynamically, only in transient memory" here.

You could certainly load a package that has prefixed-class-names and refer
to those classes without prefixes. It would be something like this:

| magmaEnv appEnv |
magmaEnv := Environment withName: 'Magma'.
magmaEnv exportSelf.

appEnv := Environment withName: 'My App'.
  import: magmaEnv removingPrefix: 'Ma';

Load your prefixed Magma classes into magmaEnv, and then write your app
code in appEnv referring to Magma classes without prefixes.
