That is some excellent Google-Fu!

I had never thought about Googling the reversed-endian versions of hexadecimal constants -- until you wrote about doing this; I think it's a brilliant idea, so I'm adding it to my search engine technique toolbox.

In summation, it's a great idea!

It's both simple and elegant!
