Believing that it's not Star Wars without the Force is the kind of thinking that handcuffs the franchise, IMO. That leads to the creation of plot lines that involve heroes who are Force sensitive using it to battle equally Force sensitive villains who use it for evil. It's no wonder that the three trilogies feel so similar.
The key to expanding Star Wars is to break away from that, IMO. Rogue One and Solo were a bit of fresh air because they focused on characters who were not Force sensitive. Even some of the better parts in TFA and TLJ were mostly devoid of Force use. The Mandalorian looks as fresh and different as it does largely because it doesn't have Jedi, lightsabers, physics-defying stunts and so on.
Perhaps the most beloved character in Star Wars isn't Luke, but Han Solo, a guy without a lick of Force ability. Perhaps the most beloved character from the Expanded Universe, Grand Admiral Thrawn, is not Force sensitive, either, as far as I know. Also, all of the large scale battles in the OT--the assault on both Death Stars, the battle on Hoth, the battle on Endor--are not Force battles. I don't think that you need the Force for it to be Star Wars. I think that you could pull off a trilogy, even, that centers on a resourceful, non-Force-using character similar to Han Solo or Poe being a thorn in the side of a non-Force-using villain similar to Thrawn. I'm not necessarily advocating for that, just suggesting that you could probably go that far in that direction and still have it feel like Star Wars if it's written well.
