Another consideration is how much clearance you have with your lifter bores. Bill M reminded me of this recently... if they are sloppy and using restricted push rods, you will be pushing more oil up around the lifters vs increasing available pressure/volume for bearings.
Although you would still accomplish the goal of less oil going up to the heads, but maybe not adding much additional volume to the bearings. The better fix is oil restictors in the lifter bores, but of course not quite as convenient as push rods!
