Can't be done.
BTW: if your booking was directly with BA, and your GF's ticket was booked otherwise, that could explain the difference. However also the fact that your booking is ex-UK and her booking ex-Canada may explain the difference in the offered MMB upgrade.
As well be sure to use OLCI to change your seats - the bassinet position will become available at T-24. At the airport you will likely be too late.
