I looked into that Febi part 10117 and it looks like it cross references to 103 200 17 28 which brings up a completely new option that wasn't available to me when I was searching in the EPC by VIN:
I'll check this part out if I ever have to replace my fan bearing bracket again. But for now, spacing the pulley out seems to be working just fine. I've driven around 80 miles since that little modification and nothing has broken yet.
