While I haven't pulled the oil pan with the motor in the car, I have pulled the motor out the top, multiple times. I can have it out of the car and mounted on an engine stand in a leisurely 3 - 4 hours, and that's dealing with a pd blower, which adds a little time & complexity. There is a learning curve associated with this, as with anything else, but you should still be able to do it easily in a day or less. Once out, the pump swap is a walk in the park, and you can do a much better job resealing the pan. I would go this route if I were you. I should probably mention that I have a 2-post lift, and dropped the engine out the bottom once. In my opinion, pulling it out the top is a quicker and easier option.
