Help me to mod my P60 drop in again

Hello guys. Being busy in another life projects take me a little apart of the flashlights game. I want to mod this triple P60 drop in. What would you recommend me today? I was thinking replace the Leds and use the same star and changing the driver of course. What would you recommend me? Where to buy it? I have some drivers but I am not sure how powerful it have to be to send the right amount of power to the Leds. Thanks in advance
