If you are going to swap the master out then i would bench bleed it. Typically you have a temporary line that feeds from the pressure side and dumps into the reservoir. You can get some short brake lines from auto parts store and bend them to make this work.
As long as the master isn't bone dry you should be ok to bleed the brakes with w/e method you prefer. I just swapped my master out and found out my bleeders were almost rusted in place. I was able to use a Craftsman Bolt Out to loosen them, I have swapped them now with speeder bleeders. I still need to change the rear hose and bleed that back half again.
