Nozzle temps on K2 and K2 Pro above 300°c

I was about to purchase either a K2 or K2 Pro to go along with a K2 Plus I have. But, I need the nozzle temp to go to at least 320°c, ideally 350°c.

Is this possible, can the head and or hot end from the K2 Plus be used? Will it fit, and can firmware etc be modified etc?

Would be great to hear from Creality on this topic.
