I received a reply from PSI today:

"HI

THE JERSEY SHOWS GREAT GAME USE AND WE ACQUIRED IT DIRECTLY. I HAVE NOT HAD THE OPPORTUNITY TO RESEARCH WHAT STYLE FONTS WERE USED FOR EACH LETTER ON THE NAMES. I WILL CHECK WITH THE TEAM TO FIND OUT IF THEY USED ANY OTHER "

I emailed them asking for what they find. I made it clear, I would like to find a style match of that lettering from 2005, but I personally have investigated this myself for hours with no luck. I hope they find something positive out because I am interested in this jersey, but also it would be a shame if this jersey sold and it couldn't even be style matched in a photograph. There are photos available from every game in 2005!
