What about dispatch `guix package -i` depending on the argument. In 
principle there will be no "*.scm$" packages so the above could be

      guix package -i package.scm

The idea behind that is to keep the number of command to minimum. In 
this case, IMO, it makes sens to merge both logic inside the same UI.

On a similar note, I like a lot the idea of Andy Wingo `guix install` 
and `guix search`.
