Yes it is possible to create a real image by combining a flat mirror with a lens
or a concave mirror.

You do this every time you photograph a person in a mirror. You are making a real
image of the virtual image of the person on the film.

I also do this by placing a "Page Magnifier" fresnel lens so that it is touching
a mirror. The combination of lens-mirror-lens will create real images in front of
the lens-mirror. Hold a candle a meter from the mirror and lens combination then
find the real image with a 3x5 card.

Have fun doing Science
