Considering that most of the guff spoken and ignored in briefings is really a waste of time… I think you should be able to brief a) the relevant bits for a safe landing - MSA, ILS frequency and ident, runway condition and length and b) how you are going to really fly this approach - i.e. 340 knots to 10nm and then speedbrake, gear, flaps on on the limits, stable ‘if’ possible, Vapp + 25 over the threshold, max manual braking to stop and evac inside of two minutes. And if you don’t have the time then don’t.
But depending on the airline and the trainer you may get given out to for not doing it the way the trainer wants it done.
