No, he did not. The Luther wanted to draw attention to the problems of the catholic church and resolve them. It was the sale of indulgences that moved him to call for change within the Church. He went public when he decided that the Pope was either unwilling or unable to correct those abuses.

The term reformation implies that it was intended to reform the church, not destroy or abandon it. The term reformation had been used as early as the fifteenth century for other movements.

Luther tried to work within the catholic church for years after introducing his 95 theses. It was only after his excommunication that he began to develop his own church. Even then he included as many Catholic elements as possible. But he refused to submit to the pope. If the church had decided to worm with him rather than against him it would have been very different.

TL;DR, he was a devout Catholic and was trying to abolish the bad parts. It was the pope that compelled him to practice his faith independent from Rome.

Yes and no, though more no than less. At the beginning, he was most definitely not trying to - he wanted to reform the errors and abuses he saw, and was far from alone in this. Many scholars of the Renaissance Humanism movement felt the same; one supporter of Luther early in his career was Erasumus, who entirely shared Luther's desire to correct abuses. Later, however, they became enemies and had a rather acrimonious public debate (see Luther's Bondage of the Will) - Erasmus couldn't support the later direction Luther took.

Because he did later take a more extreme tack - not just wishing to correct the abuses of practice like the selling of indulgences, but questioning basic doctrines and Biblical interpretations of the Roman church, such as the role of good works in salvation, and rejecting the authority of the Pope altogether. He didn't seek to leave until after he was excommunicated in 1521, but by the late 1520s and the presentation of the Augsburg Confession in 1530, it had become fairly clear to Luther and others that the Pope was not going to agree with them and maintaining their own doctrine meant separating. They didn't want to separate - they wanted the whole Catholic church to come around to their way - but they were willing to separate from it to preserve their teaching.

But at the same time, Luther certainly did not see himself as starting a new church. He thought it was the Roman church that had departed from the faith of Scripture and of the apostles, and he was going back to it. He hated to hear churches or his followers called "Lutherans"; he preferred the term "evangelical" which comes from the Greek word for Gospel. Even today, in Germany Protestant churches are referred to as "evangelisch". Luther said (cited from Ebeling):

The first thing I ask is that people should not make use of my name, and should not call themselves Lutherans but Christians. What is Luther? The teaching is not mine. Nor was I crucified for anyone. How did I, poor stinking bag of maggots that I am, come to the point where people call the children of Christ by my evil name? Not so, dear friends, let us do away with party names, and be called Christians, for it is his teaching that we have. The papists are rightly called by a party name as long as they are not satisfied with the doctrine and the name of Christ, and want to be papists as well; let them be papists; for the Pope is their master. I am no one’s master, nor do I wish to be. I share with all men the one common teaching of Christ, who alone is our master.

So he would not accept that there is a new Lutheran church founded by him, no. He would say that Christ founded the Church, and that God worked through him to bring the Gospel teaching back to light.
