Pascal has gotten around security devices in the past, so perhaps rather than blowing the door or kidnapping Kidston there could be a group effort to bypass the wing scan altogether and get the door open some other way. Though when Kidston notices the door has been opened without her help then all hell will break loose.

Getting her perma-drunk on tranquilizers and keeping her with the group as they work seems to be the safest option, even if someone will have to end up babysitting her. If they open the doors any other way then there are going to be security personnel all over them sooner or later, even with the distraction going on with the other team.
