Turn two Lemmings into both Climbers and Floaters (also known as an Athlete). After they have both climbed and descended the obstruction, have the first one become a Blocker keep the second from reaching the exit. After it turns around, make the second bash through to the others. Afterwards, blow up the blocker to allow the rest to exit.
For a less destructive solution, make only one Athlete and have it build over the exit. Then bash the obstruction, and dig or bash the stairs.
