I like Bingowings Idea...... This does execute things differently and would definatley fit better in ROTJ than a recycled a new hope begining.... A transmission is very simple indeed... What ship would you have it be bingo wings? somthing neutral I suppose. hey ok what about it is Boush on the ship a bounty hunter ship no need for lip sync either if it's boush / Leia

Ok so in your version we would simply need to see that ship rendevouz with the fleet carrying the plans? or keep it traditional USB Stick Droid Download and out the airlock?

Later we see Boush with chewbacca

Just thoughts trying to amalgamate ideas here
