You would have to radically alter how interstellar travel works.
Unlike sea travel, Traveller starships do not pass through the
intervening space, and cannot be detected or intercepted until they
reach their destination.  A maritime analogy simply does not work.

Of course you can change how jumpspace works, but it really becomes a
question of just how much change you can apply to the fundamentals of
the game world and still call it Traveller.
