Well, you could. I would bet to say that it has already been done. If by no one else than engine designers from way back when. But it would serve no purpose but to cut your load bearing ability in half. The rods get plenty of oil, if your getting plenty of oil to the crank to begin with. You'd be better served with modifying the first few feet of the oiling system in the block to help the oil get to the main galleys.
