Chorley had chance to do it exactly that today since they hosted Wolves ... Lost 0:1 though ...
As for upcoming matches ...
Wycombe vs Tottenham hopefully isn't going to be as one-sided as Spurs previous cup game ...
Cheltenham vs Man City and Barnsley vs Leicester - i'd say that if 'cupset' occurs in either of these games then it is the second one. Cheltenham should be proud if they can get (consolation) goal though ...
