It would be an interesting exercise... for a DXpedition to use custom

your QSO. I wonder what it would do to the QSL rate if you *had* to
copy the DX?

That's one heck of a good idea! Alternatively, you can just key the random
code back. If correct, you get "TU", if not, you have two more tries.

Third try without luck is a "not in log".

I like that.
