I'm not sure it's possible to kill anyone from Genshiken. They have anime nerd resilience, and I'm fairly sure anyone from F/SN would drop unconscious after just a few hours of being at an otaku convention, given how taxing to the mind and body it is.
EDIT: Moreover, do you really want to run the risk of an otaku Shirou having ANY sort of influence over Saber? The whole Grail War would turn silly in about the same time it takes you to facepalm and say 'oh God'.
Yeah... instead of Servants fighting each other over the Holy Grail, it'll be Servants fighting each other due to conflicting interpretations of canon or pairing wars or some other silly little thing...
Archer: "Say what you will but in the end, Tsuchimi Rin will end up with Asa! It's the anime canon ending!"
Shirou: "NOOOOOO!!! I can't believe that!!"
Saber: "I too share that same belief. If my interpretation is correct, Kaede would be a suitable mate for Rin from her previous experience as his caretaker."
Shirou: "BLASPHEMY!!!"
Archer: "Maybe you'll feel better if Rin started hitting for the other team."
Cue Tohsaka who just appears right behind Archer and only hears that last statement to either (A) smack her Servant or (B) start making out with Saber to cause both Shirou and Archer to go...
"OH MY GOD!!! SECRET YURI SCENE UNLOCKED!!"
