That's a pointless question. We shouldn't speculate as to what Jesus would do when we have so much evidence to indicate what Jesus DID do.
Jesus DID resist immoral authority. He made public pronouncements against them, held protests against them and threatened their power to such a degree that he was killed. What exactly was he resisting? What is the example of Jesus in resisting authority?
Power for power's sake
Jesus opposed leaders who desired positions of authority simply because of the respect and power they had. This is one of the forms of covetousness that Jesus warned against-- desiring something that you had not earned. Jesus taught that power should be given to people who show that they will use their resources or power to help those around them, not to just bolster themselves.
Accumulation of personal wealth
"Woe to you who are rich now, for you have already received your comfort!"
Jesus rejected all who kept wealth for themselves, because they were flaunting their hatred of the poor. If one has extra resources and refuses to provide them to those in need, then God rejects them as stewards of His provision. God does not provide wealth for personal use, but for community use. To misuse the resources of God, to not give generously to the poor, is to be unworthy of that stewardship.
Those who support the killing of the innocent
Political or religious oppression of the poor
Jesus pointed out how the temple encourages the poorest to give their last cent to a project that will not benefit them. Thus, they are making the vulnerable homeless and hungry, while not providing for them at all. Jesus condemns all who have power-- the wealthy, lawmakers, religious and political leaders-- for using their power to be poverty pimps-- people who take from the poor for their own benefit. These, Jesus says, deserve the worst punishment.
Selecting certain groups as outcast
Jesus stepped out to welcome those whom his society refused to welcome, and then rebuked the leadership for rejecting them. Jesus' society dehumanized tax collectors and those who did not follow their purity laws, as well as the disabled, lepers, gentiles, the poor and women, considering them all unclean, and in some cases outcast from their society. Jesus rejected leadership that rejected people according to standards of ethnicity, class, sex or arbitrary purity standards.
Systems which perpetuate inequality
"It is written," he said to them, "'My house will be a house of prayer'; but you have made it 'a den of robbers."
Jesus held a protest at the temple, because they were excluding worship for women and gentiles in order to establish support for worship for adult men. Jesus rejected this practice, even though it was approved by the high priest, the mediator of the people to God. Jesus resisted authority that made no space for all people.
Lawmakers that only create burdens for people
Because he rejected this kind of leadership, publicly and authoritatively, he was forced to carry a cross, to die as a revolutionary, as an outcast of his people, as much as a leper or traitor. Jesus, in turn, said that if we were his followers, we too would have to carry the cross of punishment from the powers that be for resisting them. If we resist authority for hating the poor and weak and for their hypocrisy, Jesus tells us we will be rejected and punished.
