So I counted 10 people who commented here so far... That is far too much for one group. it'll just be chaotic and not fun at all. 3-5 players and 1 DM per group is ideal. So if we did 2 groups, we'd need a 2nd DM, so is there anyone else who feels they could do it? I'd do it myself but I would be a shit DM and I don't want to give everyone a bad experience.
