Well, Niner's guy seems mentaly unstable... too unstable for the job.
Not sure about The Puppeteer.
SHeo's guy, not sure either.
We'd need to have them come and for us to see.
The Puppeteer could probably pull it off though he would start to lose control eventually if he was constantly forced to portray sanity. Though the bonus with him is his control over corpses. So a quick walk over to the ships morgue and chances of his success increases dramatically.
We'll need at least one more person with large access to the ship if the plan is to work. Also would we want to take control of the prison transport and have the rest of our faction meet halfway en-route or perhaps already have them there and imprisoned on board?
