I don't think having everyone is the best idea.
Realistically I expect we'd get not much progress done with the whole group involved. Might even be personality clashes. It would probably end up we'd need to shave it down to move forward next turn to speed things up.
The current group I think has the best odds and if it doesn't work out then next turn we can make a more targeted group using what we learn this time. So basically even the result of a failure doesn't seem too likely to be that much worse than just having everyone added. While avoiding the potential for inter group conflict.
There isn't an invisible threshold of maximum wrangling capacity. Less people is easier, more people is harder, some people will require more wrangling than others, some tasks will be more difficult to wrangle people on, some combinations of people and tasks could prove especially troublesome.
