Load Animator From XML without using UnityEditor

so, im building a simple project, i have to load all the animations, layers ,animatorVariables and even transitions from an XML. it all working, all classes are OK, but when i try to build it it doesnt work, as i cant use UnityEditor in my build.

 AnimatorController controller=new AnimatorController();
    /*add everything to the controller*/
 someObject.runtimeAnimatorController = controller; 

i havent found how to do this without AnimatorController, its possible? its not possible?
