Display Random Layer

Alright, I know and have used the traditional method of creating a random image slideshow: precompose all the images, make them all one frame long, and then write a time remapping expression to jump between images.

Furthermore, that will work for my current application (and it's probably what I'll do)

However, I'm curious if there's a more direct method that would be even more expandable. I was thinking of using something like "Compound Arithmatic" on a solid layer, and then writing an expression to randomly choose layers. Unfortunately, I'm noticing that none of the layer controllers (even the "Layer Control" effect itself) are keyframeable/programmable. But there MUST be a way of doing this: manually compositing, and then being able to program what layer gets composited.

The time remapping method, as much as I've used it, has always seemed like a hack or workaround, and when I'm programming, I don't like to feel like I'm hacking to make something work, unless I absolutely have to.
