You can use this code to get a readable version of a non-readable texture. Note that you should Destroy manually-created assets when you are done with them.

if (!texture2D.isReadable)
{
	RenderTexture tmp = RenderTexture.GetTemporary(texture2D.width, texture2D.height, 0, texture2D.graphicsFormat, 1);
	Graphics.Blit(texture2D, tmp);
	RenderTexture previous = RenderTexture.active;
	RenderTexture.active = tmp;
	Texture2D newTex = new Texture2D(texture2D.width, texture2D.height) { name = texture2D.name };
	newTex.ReadPixels(new Rect(0, 0, tmp.width, tmp.height), 0, 0);
	newTex.Apply();
	RenderTexture.active = previous;
	RenderTexture.ReleaseTemporary(tmp);
	texture2D = newTex;
}
