Missed opportunities for crossover episodes with The Office and various other tv shows

This may not make time sense but it makes good sense
  1. Nick Miller (the fictional character from New Girl) should have been hired in the warehouse after Roy was fired
    Him and Michael would get into arguments over how to mispronounce common words
  2. Dwight and Angela's baby grows up to be Michael Cera (the actor)
    He could play himself
  3. Joey Tribiani ( from Friends) gets hired as the new temp when Ryan gets promoted and then they compete for hottest in the office
    Joey is always looking for work anyway
