Since you are replacing the MC anyway, open the bleeders and pump away.
Just make sure you have a container to catch brake fluid as it comes out.

Don't worry about air in the system while you take it apart. You get
rid of the air in the system after all the new parts are in and you have
assembled everything. That's why you always bleed when you are done.

A 1 quart bottle may be cutting it close. I would get quart bottle and one
small bottle. Keep the small bottle sealed until you are sure you will need
it.
