No, impossible. Syncing doesn't really have to do with mining and the mining algorythm.
It does not correct. Getting better hardware (CPU & SSD) with a better internet connection will affect syncing in a positive way. Aside from that, nothing really helps that much.
Hey, I'm a bit of a newbie but I have a few antminers (the small usb ones).
I would like to add that you should preserve those USB miners. Like really clean them and put them in an air tight bag. If Bitcoin does take off, eventually they will become some sort of "antique" item and will have a better value.
