I don't know. They already announced the Jessica overlay, but only because they were sloppy enough to start removing her from the ride like the bad girl that she is. (Or that HR thinks she is)
When you look at this overall plan, even with Josh's smarmy announcement, all this really is about is a reworking of Toontown walkways and access points to accomodate a high-capacity E Ticket where none existed. They need to rework the movement of crowds within the land, and thus rework the placement of facilities and infrastructure and access points.
They've dressed it up with some new eye candy, to replace interactive attractions from 1992 that closed almost 20 years ago and have sat unused since then. They've dressed it up with some new landscaping, and reworked entry points to what attractions and rides from 1992 that will remain in 2023.
And they've clearly got some sort of ride still happening in the Roger Rabbit building, while repurposing the abandoned trolley barn next door for additional queue space.
In short, this Toontown Makeover isn't really that big of a deal.
It's a fairly cheap project driven by industrial engineering concerns instead of "immersive new storytelling". And I think Roger Rabbit is safe, although he'll be neutered and morphed into a Jessica-centered storyline that never existed and probably won't be much fun. But at least it will still spin!
