When you go on the Canoes, you can't see a thing of Star Wars Land; no rocks, no spires, no buildings, no nothing.
Because you are down at ground level on the Canoes, not 30 feet above ground like the top deck of the Mark Twain. Even though you are mere feet from the place, you can't see a bit of Batuu. Because they aren't going to let you climb 30 feet up onto the rooftops.
Using that as a guide, you probably won't be able to see a thing of Frontierland or Fantasyland when you are in Star Wars Land.
Heck, even now when you are standing a few dozen feet away from the entry tunnels into Star Wars Land, you can't even see anything peeking over the top, so I would expect it to be the exact same experience in reverse when you are standing on the other side of this berm...
Any Star Wars Land from this middle entrance area? Nope.
How about the far eastern entrance looking northwest into the land? Walking in from Fantasyland and going right up to the eastern entrance that's still walled shut? Nope.
Okay, maybe if I move way south to the Big Thunder exit and look directly north at Star Wars Land. Here's what this view looked like in 2016 as they cleared land, rerouted the River, and realigned the Railroad. Surely you will see Star Wars from here....
Fast forward to 2018 with Batuu mountains finished and massive ride buildings all built. Here's the same view...
There's just gotta be a place in Frontierland or Critter Country I could see Star Wars from. Yes! The top of the second lift hill of Big Thunder Mountain! Look fast!
