The English language is a wonderful thing, and we know some rules without knowing we know them.

‘Have you ever heard that patter-pitter of tiny feet? Or the dong-ding of a bell? Or hop-hip music? That’s because, when you repeat a word with a different vowel, the order is always I A O. Bish bash bosh. So politicians may flip-flop, but they can never flop-flip. It’s tit-for-tat, never tat-for-tit. This is called ablaut reduplication, and if you do things any other way, they sound very, very odd indeed.’ From ‘The Elements of Eloquence’ by Mark Forsyth.

Conceivably one could have dagger-digger, bogger-bagger and others like these.

If the semantics lines up with normal compound noun formation, it's going to sound just fine.

The rules for language are almost never strict, just patterns that foil the axiomatically inclined.
