Realistically she is just too far behind for that to make sense for both her and the coaches, if it were Level 5 or 6 it would be plausible but she is two+ steps behind on some really important skills. For example she needs connected back handsprings on beam, where she currently isn't even doing a single back walkover on beam. The skills missing take a full year to two years to develop, and it isn't just one skill it's one or two on every event.
Have you looked into other Xcel gyms in the area, maybe there is another one close by that trains Xcel more seriously or has older level6 gymnasts.
