Mos Isley Cantina seems like a lock for Star Wars Land to replace Backlot Express. As for the rest of the land (currently occupied by Indiana Jones, ABC Sound Studio and Muppet Courtyard), I have a few suggestions...
1. Indoor Jedi Training Acadamy: This seems like a no brainer, but moving the popular show into the ABC Sound Studio, rethemed to Dagaba, would make a lot of sense. You could also enhance she show with heavy theming.
2. X-Wing Vs. Tie Fighter Coaster: Yeah, that fan concept posted online of a dueling coaster with guns and multiple endings? That should happen. I'd replace Indiana Jones with this new E-Ticket.
3. Retheme Star Tours' Exterior/Expand Gift Shop: As it stands, Star Tours exterior doesn't make sense. Endor isn't an available destination and Tatooine isn't an ending, so why are these used outside? I'd get rid of both and replace with a sleek, metalic theme like the interior queue. The new exterior queue would be covered, more airport looking and feature Spaceport TV featuring travel tips and tricks for flying through Space. The gift shop would become Baggage Claim, and be expanded further to feature even more options. I'd like to see the Carbonite Chamber/Make a Stormtrooper become perminant additions as well as the nametags from Star Wars Weekends, with special edition Weekends ones being offered as well.
4. Imperial Outpost: With the rebels/Jedi getting all the attention, I'd like to see a strong Imperial presence as well. This is where Muppet Courtyard comes in. Pizza Planet would be rethemed to a Imperial Mess Hall and look like the interior of a Star Destroyer. It would include traditional fare with a Star Wars twist, different from Mos Isley, and it's own exclusive drinks. Stage 1 (The Muppet Gift Shop) would become an indoor meet and greet location as well as a gift shop. Mama Melrose I would be rethemed to a Jedi Counsel themed character dining featuring the Jedi Counsel. Muppet Theater I would replace with a comedic stage show with interactive elements. Lastly, the meet and greet areas near the exit of Muppets would be replaced with Darth Vader, Stormtroopers and Emperor Palpatine. The Premiere Theater would be left alone, but rethemed and used for Special Events and Star Wars Weekends.
