Producing the same luminance using a smaller LED is equivalent to running the same current through a thinner wire. At some point you're just going to be burning out the LEDs instead of powering them.
Given that you respond to that problem by lowering the current to within the smaller LEDs' reduced tolerance, then you get something too dim to use as an indicator LED.
