They should go for the gusto and recast the OT characters, and pick up right where ROTJ left off.
Luke - no idea, let me think about that
Han - crazy idea, how about Michael Rosenbaum
Leia - don't need to think about this at all, it's Jennifer Lawrence
Lando - Anthony Mackie

The Clone Wars
TV series should be continued indefinitely and if Ahsoka survived/survives to the post-ROTJ era, she should be played in the movies by Angela Bassett.
