how about adding a series resistor then the led and tap between the resistor and led to go to the 3.3 logic level circuit. I can't think of any reason this will not work on one way level shifting. I have to test this on two way level shifing. A 3.3v zener diode can be used in place of the blue LED.
I'm sure there are other creative ways to solve a problem by thinking out of the box.
