Oh god let's not start with a funeral. Would put the whole thing on a downer.

JJ will probably open with a ship flying overhead wreathed in flame under attack by unknown forces. With the Captain shouting "We've got to warn the Republic BEFORE IT'S TOO LATE!". Ship explodes, ominous hint of the imperial march.

Then we cut to a nice sunny day on Coruscant with all our old heros having a family get together (Luke is absent). The new kids get introduced.

5 minutes later half of Coruscant is laid waste and Han has died defending his family. With her last dying breath Leia tells the kids to find Uncle Luke (He's off exploring the Force somewhere). The kids still wiping away their tears run for the hanger bay and board the Falcon just in time to make a daring escape. Blasting into hyperspace and off on an adventure in a galaxy far, far, away.

That's how you start a JJ movie!

Killing off our heros in a blaze of glory would be the true way to treat them with respect IMO. Milking them or using them in meaningless cameos would tarnish the OT for me.
