You could get by with a 4-element light with straight and left arrows at the bottom. Would mean that cars turning right had to stop before going, unless you went to 5-element lights, but might not be the worst for pedestrian areas, assuming any drivers understood the effect of a 4-element light in that scenario.
I'm also surprised that with the advent of LEDs, we don't have LED lights capable of showing pure green (for any movement allowed), or only an arrow or multi-arrow (for more limited movements allowed).
