I wasn't suggesting that if the ISU chose 50 skaters, they'd be the best skaters at Worlds. What I was suggesting was a compromise of a compromise:
All of the skaters who would qualify now, qualify. If the federation decided not to send a skater, that would open an extra spot for the stronger federations's skaters.
If there were a qualifying round for the balance of the spots, it would cost money. A cost-free solution would be to say that everyone who has a personal best at least as good as some criterion, like better than the top 12 who received two GP berth, who qualfied for their National team, and who were in the appropriate division (Jrs./Srs.) in the current season, could be eligible to participate at Worlds. If there were more skaters who qualified, then the highest scores would make the top 50, and the feds would be required to pay the expenses of the skaters.
For example, the top 12 Ladies competing in GP this year were:
1 Kimmie MEISSNER
2 Fumie SUGURI
3 Elena SOKOLOVA
4 Yukari NAKANO JPN
5 Sarah MEIER SUI
6 Joannie ROCHETTE CAN
7 Emily HUGHES USA
8 Susanna POYKIO FIN
9 Kiira KORPI FIN
10 Yoshie ONDA JPN
11 Carolina KOSTNER ITA
12 Mao ASADA JPN (because Cohen didn't skate GP)
There were 45 participants in the SP in Tokyo
Personal Bests among senior women:
If bold, they made their respective teams anyway. If italic/bold, they would have a chance to qualify under the new rules.

Three women, all from Japan, would have qualified for the SP at Worlds 2007: Suguri, Sawada, and Onda. If the cut-off is 48-50, then all of them would have competed in Tokyo.
This isn't foolproof: while it could help skaters who are being held down by their federations, if their federations couldn't influence world judges to hold their skaters down at GP, 4C's, Euro, it this would allow federations to fix nationals, so that any skater who would qualify under the new rules would be held down, to maximize the number of skaters from that country. Plus, if I were a small nation, I'd be willing to take some form of consideration from a big fed to not send a marginal skater, opening up a spot for a big fed's skater.
The other possibility is a qualifying event the first day of Worlds, like the quali rounds a Wimbledon, which would cost $$$, even if the feds paid to send the skaters.
