When you remove the calipers your going to introduce air into the system no matter how fast you cap off the lines.

Since the calipers are lower than the brake reservoir, removing the calipers does not introduce air into the system - that's why the fluid is leaking out. Yes, when you put the calipers back on, they will be full of air that will need to be purged, but in no part of the process should air be getting sucked back into the system.
