Getting a Tactical/Hunting 18650 in 2700-3000K?

Wanting to get something like the Klarus XT32 with a warmer high CRI but with a min of 1000 OTF lumens for at least 10mins. Can anyone do this mod work?

Do you need 2 cells?

Funtastic is making a great hunting flashlight, It will not be 2-cell but modable so High CRI is a possibility
