I picked those examples at random based on the best images I could find of jersey histories. I could easily produce others that better fit your precise criteria and we both know it, but I'm not playing that game. Address the substance of the argument or move on.
BTW, PSG was founded in 1970 from a merger of Paris FC, that was only a year old, and Stade Saint-Germain that'd struggled for decades and left little impact on PSG design wise. For all intents and purposes they were a new club. Their financials were patchy at best for most of their existence until the Qataris bought them out in 2011, and topflight soccer is a more competitive market than anything in Australian sport. Yeah they've got a global audience, but they can lose that audience to a dozen different clubs from half a dozen different countries in a heart beat if they aren't careful. A couple bad years or a relegation and suddenly most of those PSG fans are spending much more time watching their e.g. EPL side, and the same goes for all major soccer teams.
Almost all of those changes above are significantly larger than any Souths have made with the sole exception of the Minties jersey. That's also just a small sample of the changes they've made, and doesn't include their away or alt kits that are way more adventurous than their NRL equivalents on average. That picture doesn't do the Utd jerseys justice either, as the fine detail in many of their jerseys is completely lost in that picture unfortunately.
The safe money would be on most neutral observers disagreeing with you, but I wasn't seriously suggesting that the Roosters should copy PSG's designs anyway. I honestly find it kind of sad that you seem to be of the position that there's such a bankruptcy of creativity at the Roosters that they'd be incapable of coming up with an aesthetically pleasing design on their own.
