It would be very easy to use a constant current to drive the LED and simply short it periodically to provide the blinking without supply current variations. You would still have short transients in the drive circuit, but these should be much easier to filter.
Agreed. You could also have a pair of LEDs and alternate which of them is lit.
Then, to reduce the impact on the PPS signals, the LED on/off could be forced to be phase-shifted to the PPS.
