Did she explain it was a long shot?
There are two main issues with this approach:
1. It is very difficult to get a meeting waiver, I think I have come across it twice both in very exceptional circumstances.
2. If you do get a waiver it is very easy for a K1 to be closed out by the Consulate, they issue a 221G, send it back to USCIS and it dies. I find it difficult to believe the Consulate would be sympathetic.
Nothing is impossible, I have seen too many odd cases but this is really up there as effectively it requires a double Hail Mary.
