Beg to differ on that one... Especially when talking about spirit sigils in general.
Elubatel is a very special spirit, for sure, but I would not bet highly on a thought that anything can be used as his sigil as long as it has meaning for operator. To me this seems a little close to the notion that "spirits are parts of our consiousness".
Though I admit it's just a guess on my side. Haven't tested "anything" and, frankly, don't intend to .
