I have a new bike with a 120mm 2016 32mm Fit4 dampered Float. No Kashima coating. (C2KD)

I also have a 2014 150mm 32 factory fork that has little use, but has kashima coating. (CM95)

Would I be right in assuming that I can swap the 2 CSU’s over without issues and keep the lowers and cartridges together.
Basically, I want to keep the 2016 full bike as it is, but add the kashima as it’s all a matter of style. Stickers on the full bike are color matched to the frame.

No one csu is 80-120mm chassis, the other 130-150mm chassis , most likely different internal bore diameter.
