Changing oil gasket without draining oil?

I have a minor leak that spreads across the bottom of the oil pan caused, I think, because the wrong type of gasket was used at the last oil change.

The place that did it said that they would be willing to change the gasket. They said they could do it without draining the oil by applying a vacuum to the oil fill tube and I guess blocking off the dip stick hole so that the oil doesn't come out while they change the gasket

Has anyone ever heard of this being done successfully? Can the vacuum cause any damage to any systems in our 7.3 engines?

The old vacuum trick works very well, done it on cars with 5 quarts and up on some bigger hydraulic systems with 40+ gallons of oil. Don't really lose much, if any oil, and being the crankcase vent is open, and with the hole from the drain plug, the vacuum created in the crankcase will not harm any seals.
