U should have done it easilier when the committe is still working on
applications. Probably they cannot do much on it now, but it lose nothing to
try. If ur gf is here, ask she to talk to them directly.
Tell them that ur gf is very interested in the program. If she receive
similiar offers, she will accept ur offer because of the family reason. If
there is any obvious weakness of ur gf's app, explain it a little as well.
