My advice would be to decide whether your LS deck is going to be superfriends or unblockables, take out the pods that conflict, and replace them with things that more directly support your chosen theme. As it stands you're half-assing both, which is a recipe for failure.
If you're sticking with unblockables, drop Chewie and the Falcon, replace them with Defense of Yavin IV (to make your vehicles cheaper and give you Astromech Upgrades and Rebel Assaults) and Prepare For Evacuation (protector Y-Wings, nuff said). Now you may be wondering, why am I keeping Han? Well, for starters he brings with him Swindled, giving you a total of four in your deck. I shouldn't need to tell you what a valuable card this is for an unblockables deck. But there's more - Han himself can be an excellent supporting player for your sleuths. By sending him in first, you can potentially neutralize 3 low-cost chuds who could have blocked your sleuths - one with his reaction, one with his 2 points of targeted strike damage, and one with his tactics icon. (Of course this can make the whole turn hinge on a single edge battle, particularly if they block with tactics, so plan accordingly.) Finally, his objective can be a great help to keep your sleuths flying (and, again, to neutralize potential blockers).
If on the other hand you want to focus on characters, obviously you drop the sleuths and blockade runners. From there you can stay with Smugglers and bring in Lando, or dip into Jedi for Luke. Either is a solid choice. You've then got a lot of options for how to round the deck out - Yoda, Obi-Wan, Old Ben's Spirit, and Guardians of the Peace for Jedi, Lobot*, Echo Caverns, Undercover Dealings, and Call to Arms for Smugglers. (Note that most of the Smuggler pods will work just as well in the Luke version.) You could cut the Falcon, but it synergizes so well with 'big gun' characters thanks to its swapout action that I wouldn't recommend it. Nothing like knocking out one objective with the Falcon then pulling it back to drop in Luke or Chewie.
*Just kidding. Nobody uses Lobot, he's terrible.
