I do recall hearing/ seeing this sot of thing on occasion. I wouldn't change more than one treble to single per bait.

for instance, I don't think I would change out any hook on the belly of crank as the muskies broadside the bait a lot and its too easy for a single hook to lie flat against the bait and render it useless.

the tail hook on the other hand I would be willing to make the change: think stinger hooks. from behind the hook is more likely to be in the correct position for hook set. in fact this is the one hook I have seen as a single from the factory and think of spinner baits: they only ever have one upturned hook- and maybe that stinger. that would certainly save you a tangle of fish and bait on a broadside hit.
