This might be what is necessary to make skating "mainstream" for the general public again - but I'm not sure that's the most realistic goal in this day and age, when more and more people are watching things on their computers and not on network television, and people can be way pickier about what they watch.
Being "mainstream" in the public consciousness isn't vital to $$$$ and success, I'd argue, looking at what Abraxis12345 mentioned re: competitive video gaming. Niche markets have the potential to be huge, and they don't require an American star. Naturally, USFS's responsibility is to US skaters, but it's possible that "what's good for the goose is good for gander," and that piggybacking on the popularity of international skaters is good for USFS skaters in the long run. If hyping Japanese and Russian champions gets people to tune in, then it's great.
I thought the whole idea was to make skating more "mainstream"--or at least increase its audience closer to the levels we saw back in the Kwan, Lipinski, Cohen eras. Hyping non-American skaters will never achieve that goal in the US any more than hyping US skaters in Russia would have any affect on interest there. If US Figure Skating had a dominant star among the ladies, interest would grow. I'm not sure it would ever reach the levels we saw in the 90s and early 00s, in part because of the scoring system and also because TV coverage is poor. I miss the days of ABC coverage, with Dick, Peggy and Terry Gannon, all of whom actually attended the big events and reported live, even if the event was shown on tape delay.
