In Europe, in normal vsisbility conditions an "expedite" can be asked whith one on finals at 3 , even 2,5NM .it is done in airports with single runway ops and high capacity ( e,g Gatwick, Geneva, etc..) It is also normal for a crew to reply "unable" if they are not ready , the clearance " is almsot always preceeded by a question like " ready for an immediate departure ? etc..
Definitively not in LVP (i.e. with low vis procedures in place) But not exatly sure of the US/FAA tolerances. I howeververy much doubt that their book allows that. but not my area..
