A crank scraper should run quite close to the counter weights and crank pins further reducing the amount of oil mist being flogged around.
Crank scrapers are usually designed as part of a well thought out windage tray - see the insides of the 4A GE and you will see the scrapers are merely a series of small punched louvres.
There is some free horsepower with the scrapers and I would include them as part of the windage tray - remember too that windage trays are to help re-coalesce the oil and reduce its tendency to be aerated when it returns to the sump.
