Same general idea,  but an image intensifier plate would probably not work well.  They are usually thinner and are cut at a bias so the electrons ricochet along its length.  You might be able to mount one so that it cancels the bias angle.

They are made by stretching a bundle of hollow glass tubes that have been filled with solid glass rods of a different composition.  The original bundle can be very large (like over a meter) and is shrunk down to like 100 fibers per millimeter.  It is then sliced and polished.  Often the slices (or the pulled bundles) are joined into a bigger plate.   Then the inner solid glass is dissolved out with a strong alkali. The hollow tubes are coated with a photoelectric material.
The image from the tube is inverted using a "twister"...  a coherent fiber optic rod that has a 180 degree twist.

---------------
Do you know if the collimator is made from an uncoated microchannel plate?
If so, an old, broken Gen II image intensifier might be a viable source.
