Hello,
I made a small Texture Combiner tool for Unity, which you can download here:

TextureCombiner.cs

using UnityEngine;
using UnityEditor;
using System.Collections.Generic;

public class TextureCombiner : EditorWindow
{
	[MenuItem("Tools/Texture Combiner...")]
	static void Open()
	{
		var w = GetWindow<TextureCombiner>(true, "Texture Combiner");

TextureCombiner.shader

Shader "Hidden/TextureCombiner"
{
	Properties
	{
		_MainTex ("source", 2D) = "black" {}

		_TexR ("R", 2D) = "black" {}
		_TexG ("G", 2D) = "black" {}
		_TexB ("B", 2D) = "black" {}
		_TexA ("A", 2D) = "white" {}

It simply combines up to 4 textures into an RGBA one.
You an also load back a generated texture and it will find back the source images, provided they are still in the project.

Example combining some noises:

Feel free to use it however you want!
