2 Jumah prayers in same place

Answer 1

I think that its ok. The masjid in my area has 2 jummah prayers and 3 eid prayers every year to accommodate the crowd and the schedules of people.

Answer 2

Many Uni's have the jumah salah, one after the other do to space. so i'm sure you can do this. or if you have internet connection then you can put live ipcamera and can view it from anyother location and everyone can hear the same prayer.
