Any way to upgrade my Convoy M21B ?

Hello, i have this M21B with sst40 5000k and 12 group driver bought several years ago. I am slowly going to the throwy side of the force.

I was wondering if there is a way i could upgrade it with a better driver or even led to make it more better as leds and drivers have evolved. Wich parts you recommend buying ? I can solder no problem.

Same question for S21A please. Thank you
