Two possibilities:

 1. If you're using v200, then you can probably export from one module
    everything that you want to put into a namespace. Then it's just a
    matter of requiring the module in the newly created namespace
    (possibly attaching it first; see `namespace-attach-module').

 2. I could add support for a 'clone flag to `make-namespace'. I
    haven't done this yet because I haven't encountered a situation
    where option 1 wasn't better.
