Can I put a THREE.js material on a gltf model?

Question

Im currently working on my portfolio in A-frame. I'm trying to change the material of the objects to a wireframe material, i'm using the wireframe material (MeshBasicMaterial) of THREE.js to do that. If I put this material on objects like "a-box" or "a-sphere" it works, but i need to put this wireframe material on my 3D gltf model. Is this possible?

This is my script to call the material:

AFRAME.registerComponent('wireframe', {
             dependencies: ['material'],
             init: function () {
             this.el.components.material.material.wireframe = true;
                }
            });

<a-box position="-1 0.5 -3" rotation="0 45 0" material="color: blue" wireframe></a-box>

It is possible to modify the material on a gltf. One way to do it is to drill into the THREEjs level of the mesh inside the gltf, and create a new material and assign it a wireframe property.

 AFRAME.registerComponent('tree-manager', {         
          init: function () {
            let el = this.el;
            let comp = this;
            let data = this.data;
            comp.scene = el.sceneEl.object3D;  
            comp.counter = 0;   
            comp.treeModels = [];
            comp.modelLoaded = false;

            // After gltf model has loaded, modify it materials.
            el.addEventListener('model-loaded', function(ev){
              let mesh = el.getObject3D('mesh'); 
              if (!mesh){return;}
              //console.log(mesh);
              mesh.traverse(function(node){
                 if (node.isMesh){  
                   let mat = new THREE.MeshStandardMaterial;
                   let color = new THREE.Color(0xaa5511);
                   mat.color = color;
                   mat.wireframe = true;
                   node.material = mat;                  
                 }
              });
              comp.modelLoaded = true;
            });   
          }
        });

<a-entity id="tree" gltf-model="#tree-gltf" scale="5 5 5"  tree-manager></a-entity>

Here is a glitch that shows how.
