How realistic in terms of performance is it to simply increase the sample size? Many images that we might want to model won't necessarily have one simple light source, so there is value in sampling across the entire hemisphere. If we simply sample much more rays to reduce noise, would this be feasible or too inefficient for many cases?

It depends on the hardware of course, but keep in mind that increasing the sample size increases the work done by a multiple of however number samples you do per pixel, so if we go from 4 to 16 samples, per pixel, the scene may take around 4x the time to render.
