Replacing GameObject with Another one WITHOUT losing its components

Hi everyone,
I couldn't find my question's answer. If there is one, sorry for that. But first let me explain.
I have 2 different 2D characters. I have used the 1st one and worked on it couple weeks. But then i've changed my mind and i wanted to use 2nd character. Can i replace the 1st one with the 2nd one without losing all the components (like rigidbody2d, collider, scripts etc.) I just want to change its visual. A different sprite but with same properties.
Thanks in advance

 

You can create a Prefab Variant fo your original character and then change only the parameters you want to change in the new variant

 

Just remember that prefab variants are very risky since you have to plan many things upfront, and you will not be able to change inheritance chain later.
