Create an Empty GameObject, then you can put that to a prefab.

In Unity, GameObject > Create Empty.

However, If you want to then attach a 3D object to it, you'll have to make the Prefab the parent or child of that object.

I think you can do that by placing all the scripts on an empty gameobject. make that gameobject into a prefab, then placing the prefab onto anything that you like.

But you must be careful what scripts you place in the prefab taking into account the variables it has and names it has stored.

i don't know way to easy move configured component from one object to another with saving target's configured components... but...

i found an easy way to create a preconfigured components on gameobjects. script below makes a menu with fast adding preconfigured rigidbody to object. you can use this way to add any preconfigured component. also, you can do it in runtime (just use method's content in runtime script)

also, don't forget that you can set default values for monobehaviours in script. then script will add with these default values.

using UnityEditor;
using UnityEngine;
using System.Collections;
public class FastMenu : MonoBehaviour {

    [MenuItem("UnityAnswers/Add Preconfigured Rigidbody")]
    static void AddPreconfiguredRigidbody()
    {
        GameObject go = Selection.activeGameObject;
        if (go)
        {
            Rigidbody rb = go.GetComponent<Rigidbody>();
            if (!rb) { rb = go.AddComponent<Rigidbody>(); }
            rb.mass = 100;
            rb.drag = 0.5f;
            rb.angularDrag = 0.5f;
            rb.constraints = RigidbodyConstraints.FreezeRotation;
        }
    }
}
