C# Instantiating a Gameobject with a Flat Sphere Collider

[Ochreous]

Is it possible to create a gameobject with a collider upon instantiation? I want to Instantiate a gameobject that only has a flat sphere Collider but I don’t want create it as a prefab and then instantiate it because I want to create the scale upon instantiation. I’m unsure how to instantiate a gameobject and then add a flat sphere collider to it. Would you create the gameobject as a variable and then use it?

using UnityEngine;
using System.Collections;

public class CreateNewGO : MonoBehaviour 
{
	GameObject go;
	GameObject meshObject;
	
	void Awake()
	{
		go = GameObject.CreatePrimitive(PrimitiveType.Sphere);
		go.transform.position = transform.position + (transform.forward * 5)+(-transform.up);
		Destroy (go.GetComponent<SphereCollider>());
		
		//Change mesh of go. Will load object from Resources/Prefabs/Put name of your prefab here.
		meshObject = (GameObject)Resources.Load ("Prefabs/NameOfYourPrefab");
		go.GetComponent<MeshFilter>().mesh = (Mesh)Instantiate(meshObject.GetComponent<MeshFilter>().mesh);
		
		go.transform.localScale = new Vector3(3, 3, 3);
		go.AddComponent<MeshCollider>();
		
		
		//Test collider with rigidbody
		GameObject test = GameObject.CreatePrimitive(PrimitiveType.Sphere);
		test.transform.localScale = new Vector3(.3f, .3f, .3f);
		test.transform.position = transform.position + Vector3.forward * 5;
		test.AddComponent<ConstantForce>().force = Vector3.right;
	}
