If i can switch lawyers, would I be able to get more time before court or mediation due to getting a new lawyer? Would the court allow a change

You are the employer, and can hire and fire attorneys at will; the court may -- or may not -- alter already-scheduled dates based on a change of counsel, as the court balances "due process" concerns with the rights of the parties to have a timely determination made.  If you have reached the point of no return with current counsel, then confer ASAP on this specific question with all possible replacement counsel you are interviewing.  With only a week prior to mediation, you will have to move quickly.
