Not a new idea but an interesting one. Been discussed on stack exchange / physics for a while, here is a thread.

Since there are gravitational lenses, are there gravitational mirrors?

Gravitational lensing is an observed phenomenon. Can one have a gravitational mirror? A slightly unrelated question: Can gravitational waves be reflected?

Its possible to use gravity as a lens, they should be possible to use it as a mirror also. Nice idea.

The Solar Gravitational Lens will Map Exoplanets. Seriously.
