It would be similar to the tower in California. But the Hollywood version thankfully has the luxury of having more space to showcase the characters. The line will be an attraction on its own. In it you will be shown the different suits that Edna Mode has made like in the first film.
An actual Edna animatronic will showcase them while sitting in a chair above the spectators. It will be similar to the Rocket Raccoon one in location. The animatronic will be in the newly rethemed study section of the line. This is where she shows the different costumes for "The Incredibles". Perhaps a few costumes will still need some more testing out though. The ride itself will show our favorite super family and Frozone testing out their different abilities in different ways. They'll be interrupted though when supervillians decide to crash the party.
