I took a stab at it for you...

There is no exact match for the jersey of course, and I had to pick 2 of the three logos (USC trojan head, USC "SC" logo, Nike swoosh) so I went with the 2 USC logos.
Some things are not evident from the pictures. For instance what is the logo (if any) on the side of the helmet? I went with the "SC" letters to differentiate it from the original helmets.
In lieu of the Nike swoosh on the pants I put the trojan head logo. I left the area where there would be a Nike swoosh on the jersey empty.
The only other major issue is the color on the side of the jersey. There was no way to get it to match the jersey's inner stripe, so on the home jersey it's yellow instead of red, and on the away jersey it's white instead of yellow. I figured the shoulder stripe colors were more important.
The field, stadium, coach, roster, recruiting pitches, and alternate uniforms all conform the the regular USC settings. I did not rename the players obviously.
I can make changes to it if you like.
