The FAQ answers that one...

* Is it possible to use Ronja together with a mirror halfway on the path? 
Yes, it is possible. However, ordinary mirrors from glass cutter's shop are 
not perfect planes, so they spread the light a little. So the signal is a 
rather weaker than if the mirror was not there. It is also advised to have 
the mirror bigger than lens diameter to make it prone to misalignments, air 
waving and imperfections in the mirror. Also the mirror should be protected 
from dirt and weather by some kind of hood and the back of the mirror must be 
waterproofly sealed in order for the reflective layer not to be damaged by 
moisture over time.

it _is_ doable.
