Archer Emiya and Emiya Alter drunkenly exposed(?)

                                    

                                          
The song is "I can't smile without you by Barry Manilow"
This idea came to me today when I thought back to Hell boy 2 at the end of the movie
Location: Chaldea (imagine they have a stage area to do musicals, band performances, karaoke if you want etc. but the plot twist is you could record the performances with preinstalled cameras, but the Emiya's don't know that)
Just imagine Archer Emiya and Emiya Alter decide one day to relax and hang out drinking alcohol made by Alter and eat snacks made by Archer, and they eventually get drunk (I like to think due to the difference in cooking between the two, Archer is the better chef, while Alter is better at alcohols/drinks and is known for his junk foods) and they eventually stumble upon the musical room (pretend no one is there for the day) and decided to mess around and started to sing this song together (karaoke style) but in their drunkenness they didn't realize that the room has the option to record their performance (think a video of the people singing etc.) and could publish it to the internet of Chaldea if the option is on (based on luck it *just so happens* that Elisabeth Bathory was their before) and their performance will be shown to others and Archer just so happens to have his hair down in Shirou's style. Once done singing and they leave since the save option was on, the video was published, and the other servants and staff of Chaldea will find out about the video.
The next day after the video release they happen to encounter Artoria (and her counterparts), Rin/Ishtar (counterpart plus Ereshkigal), Sakura/Parvati (Sakura counterparts), Luvia/Astrea, Illya (and counterparts plus Miyu), Taiga/Jaguar man, Irisviel, Medusa Rider, and Kiritsugu who are just now watching the video (Kiritsugu got forced to by Irisviel and Illiya and co since they watched as a group and the rest did as well in groups except Luvia who watches on her own device) and they happen to recognize Shirou in Archer and look at him in surprise and recognition. 
Thus, leading to a whole lot of problems for the two Emiya who are Archers.
