Its not steady to rely on such a small VR1 margin. Heat up cycle can disrupt it. Better bodge a 4th led to widen that voltage and use a higher value R1. Or stick a blue led in the now gang of 3. Better aim at 0.7A also.

That's a void question if you will not decide the new leds scheme and estimate the voltage margin first. Use the Excel calc.

That one takes you to 0.647A, go lighter load. 10 Ohm for 500mA @ 5V.
