Is there a reason why there is no such method?

Because of the same reason there is no Sets.transform. see
http://code.google.com/p/google-collections/issues/detail?id=219 for a
short discussion. To keep the TransformingMap at a consistent state,
you would have to provide a truly bi-directional function. Kevin B.
has hinted that future G-C releases may contain a two-way function
interface which may enable Maps.transformKey and Sets.transform to be
implemented.
