Thats actually not a bad idea. However, I dont think that having a section would be the most conducive for singles to meet and socialize, sinces in venues like the Siyum Hashas you are basically talking to the people seated immediately around but thats all.
This would still be a great place to capitalize on the fact that it is one of, if not the largest gathering of jewish people. I think that having an event room or two for a shidduch event with a bunch of shadchanim present.
