The factory baffle does not serve as a scraper. It has 2 purposes. The baffle runs all of the way to the forward portion of the pan. Oil drains back underneath the baffle and the baffle keeps the windage created by the crank from picking it back up before it drains into the sump. The baffle also extends partway over the sump to prevent the crankshaft from pulling oil out of the sump with the high speed wind it creates. The baffles are important and I suggest you have your machine shop put it back in.
