thanks to all of the guest actors Star Trek TNG had, you can go this way:
Brady to Dorn in the Dodge commercial
Dorn to Ray Wise in the TNG episode Who Watches the Watchers
Wise in X-Men First Class with Bacon
That is the only shortcut I could find, most of the other TNG guests (Ashley Judd, Tony Todd, Terry O'Quinn, James Cromwell, Famke Janssen, and many more) are the same number of steps as Patrick Stewart was.
