If it intonates perfectly, and the string alignment doesn't bother you, then the best solution would be to put a bridge cover over it.
As the bridge is misaligned, then there is no drop in replacement. If it's slightly off as you say, then moving the bridge over, even half a mm will increase the size of the screw holes, meaning the screws won't hold the bridge solid. You will need to fill the holes and drill new ones with new bridge or existing one, which is a pain in the a***.
