A primarily black jersey without the circle and white background behind the logo would look nice. With the whole "Jersey's team" theme, maybe just the J in stead of the N as well would make for something different.
something like this actually, but a little more black in the mix. Get rid of the white piping, and make the red a lot smaller. Make the shoulders all black too.
Also, it might be stupid, or impossible, but maybe add the flame design from Marty's helmet at the bottom of the jersey, and on the ribs. Probably would need permission from Marty's artist though.
