Could you trial a new vaccine on people who are already vaccinated and compare that to a control group of other already vaccinated people?

Well some of the trials started a while ago when there were more immunologically naive people. And at this point, they're moving away from worrying about that since barely anyone is going to fit that category, so why bother trying to use them as any kind of reference point?
