Like you've worked out, there isn't a way to stop air getting in the system after taking one of the pistons out.
I did mine by taking off the calipers and using a footpump to push each piston out. I cut an old inner tube valve out and sealed it into where you screw the banjo bolt, you can use compressed air if your carefull because the pistons do seem to shoot out at 100mph!
Take your time with it, clean out all the grooves where the seals sit and red rubber grease the pistons when you put them back in.
