Unique Consulting Recruitment Situation

I am currently an undergrad senior and completed the interview process for a boutique firm several months ago and was told that my interviewers wanted to advance me but the firm was freezing their Class of 2024 hiring. I've kept in contact with the firm but have just been kept on the hook. Repeatedly being told that they'll contact me when they'll need to add more heads.

I am sure that this is the type of work and firm that I want to work at. Is it crossing a line with my relationship with the firm to ask to be included in the next class of hiring (probably 1 year later)? Should I just wait? I have still been recruiting but haven't gotten an offer that comes close enough to what I'm hoping for. I am asking because they should be approaching the time period of the start of Class of 2025 hiring and the start date for Class of 2024 would be at the end of this summer. Any advice is welcome.
