I'm a bit confused at how you would focus your light sources.
You will need to focus them down to a point on the galvos / piezo's, would you
then have the light go through a second lens to re-focus it for projection? And
would the second lens need to be deformed in such a way as to correct for the
edges of the projection (which will be farther from the source than the center)?
It would of course be more convenient if the projector could sit on the ground
and project upwards, which is even more of a focus problem.
