I like this idea.
A select number of Wild Card spots in non-Olympic years to be determined after Europeans and 4CC would be exciting, and would incent skaters and federations to keep improving their depth through the season.
I'm getting a bit off topic, but I'm also wondering there would be more appetite for this if it were balanced by the opportunity for smaller federation skaters to get extra spots at Worlds, Europeans and 4CC at Nebelhorn as there is for the Olympic Games.
Yes, bigger overall ISU events are more expensive, but we've also seeing a wave of new countries in Asia that are gaining interest in the sport. And fans in these countries may support Russian ladies not just their own.
