Suggestion Oversized Party Option

I think mob damage would also have to move up in proportion but could work

Ideally, damage will always go to the one tank all the time regardless, so damage going up would just mean you force more healers. AoEs will hit more players demanding more AoE healing, because you can no longer assume you can simply do 3 single target heals spread over time.

For that reason, I don't think more damage or more healing are necessary for this to work.

Some bosses that pick targets based on roles may behave weirdly, though. Magitek Predator in Baelsar's Wall, for example, seems designed around targeting/chaining all the DPS in the group. An oversized group may make it weird, but don't think it would be game breaking.
