What would you do with it that you couldn't with an escape suit? Pop up to the surface, have a quick look round to see if you can spot any ships, and then swim back down to give everyone a status update? Unless you're next to the beach, hard to envisage a scenario where you'd leave the submarine without knowing there was someone on the surface to pick you up.
Although (some) submarines do have the capability to deploy and recover divers at depth, the systems required to do so are a lot more complex than a basic escape trunk.
Best hopes and wishes for a successful outcome....
