I forgot one thing. It´s not impossible. Look at Kostner. How many times did people say (including her) that she had peaked - a few times I think. Also, there could be a backlash in the scoring of ISU. Maturity may become more important that it has in the last few years.
I think there is still room for improvement: Hit the 3-3 when it counts; find choreography that suits her; try to get a true lutz and maybe repeat that jump in the LP / use it in the SP. She was doing a 3(f)lutz-3loop back around '08, so maybe she could do that, but just do it w/ proper edges and landings. I know it's a big ask but these are avenues she'll have to travel to get the respect of the judges and be a podium contender.
Judges are willing to reward her when they see improvements. She just needs to find a way to keep improving and stay relevant
