If in-game carry-positions were customizable (which they aren't), i would consider using this one, for a class of large axes:
I.e just carry it around, in the left hand, in balance near their cutting end. It looks very natural to me.

That one might look nice in, say, a peaceful woodcutters village, and even in battles... Imagine seeing the axeman above, say, throw knives with the right hand (while keeping the axe balanced in the left hand), and then switch to the axe with both hands to go in H2H. Because that's what would happen I think.
(only, modders would need to make sure that any troop carries such axes had no other two-handed weapons in their arsenal)
