Can late-night musings cancel out other late-night musings?

So basically, I'm an idiot. There's no way my method of "doubling up" on LEDs is going to work.

No matter how you slice it, there's no way to light up just 1 LED.

I'm too tired to think about this anymore, but my solution will definitely involve some shift registers or a bigger micro controller.
