Unified Pacific Islands team?

First of all, I'm a rugby newbie, I just got into this sport and I'm hoping to watch the World Cup for the first time this summer. So I'm not sure if this idea has been tossed around and shot down.

I just learned of the Pacific Islanders rugby union squad that has played in friendly tournaments, and although they've pretty much lost every single international match, the scores are very respectable. I just think that Tonga, Fiji, and Samoa are going to find it harder to compete against the big boys as rugby becomes bigger worldwide, as they are already minnows in the World Cups. I was just thinking that if the Pacific Islands entered as one team, it could be a very competitive team that would help those nations. Plus, you might gain added talent from nations like the Cook Islands and Papau New Guinea.

I mean, where would be Caribbean nations be without the West Indies cricket team? Many of the sport's legends would likely have been lost if those nations competed on their own. Plus, their team pretty much pushed the sport of cricket worldwide, especially in the 70s-80s. I don't know, this is just a floating thought that I had.
