How about some custom combination functions and scriptable shooting? (like, you take several shots at the same parameters in sequence and compose them together with additive blending to simulate shooting in B mode, or you take a sequence of photos each focusing on a different "quadrant" on a grid and then compose them shots together resulting in an image that kinda got the right focus everywhere at once. or you take an sequence of shots doing all the possible combinations of focus and exposure (preferably with some indication in the file name or in the metadata about the parameters) to use with a visualizer program that changes the focus and exposure live as you move the mouse cursor over the image making the point/area under the cursor have the best parameters, kinda like simulating an eye looking at the scene live. or you could shoot a sequence and compose the images with only the pixels brighter than the existing pixels being inserted for a different looking light painting etc, possibilities are endless)
