The wear on the edge will not be a problem. I have one pulley I got from RPM Outlet that has a little wear on the edge (offered a discount when I bought them because of this). The pulleys are wider than the belt to begin with, and the belt rarely if ever will be on the edge.of the pulleys. The rims on the idler pulleys and tensioner will determine where the belt rides. And it is entirely possible to shim the tensioner with washers to put the belt where you want it on the pulleys. That's what I did, put washers on the tensioner that move it forward a hair. The belt rides on the back rim of the tensioner, but is centered on the idlers and upper/lowers.
My belt originally wanted to stay on the rear edge of the upper and lower, and rode the rear rim on the idlers, when I first installed them. When I put Brett's manual tensioner on, I took the time to play with various thickness washers on the interface between the tensioner and the pulley bracket. It took numerous on and off sessions, but I finally got a set of washers that positioned the belt in the center of everything except the tensioner pulley. I can live with the belt riding the rear rim of the tensioner pulley, it is causing no excessive wear since the rim itself is smooth.
From what I see, you could take a Dremel tool and smooth the rough edges, wouldn't worry about it myself. Then have the pulley re-powdercoated or anodized. The pulleys are hard aluminum, so could chip like that if dropped. I would use it myself, and just do what I said above, adjust the belt position to keep it away from the damage. You could always flip the lower around, and put the damage front or rear, depending on where the belt wants to ride on it.
From the two lowers I have, they both have the same distance from the center to the edge, so they can be mounted either way.
btw: both sets of cogs I bought came with two lipped idlers. Looks like yours doesn't even have one. Relying solely on the tensioner pulley to keep the belt on all the others. I have two unused RPM Outlet lipped idlers, if you should possibly want them. They're black and not been used since I use two of those custom idlers made by chickenwings_85.
