Silver Service as well: https://www.amtrak.com/content/dam/projects/dotcom/english/public/documents/menus/routes/Silver-Service-Dining-Car-Menu-0424.pdf
Unless they are doing two separate routes, they'll have to decide between going through Macon or going through Athens and Augusta. The former would be a shorter distance but the latter would serve a larger population.
If they only use accessible coaches on those trains it seems feasible. For example:
Train 1: Other sleepers - Accessible sleeper - accessible cafe - accessible coach
Train 2: Accessible coach - accessible diner - accessible sleeper - other sleepers
would combine at the coaches and still maintain...
I counted it because along with the ADA room there are additional rooms below but if you can argue the car is "used primarily for non-revenue purposes" you are right.
Based on this from Amtrak's proposal
They need four accessible rooms because there are four sleeper cars counting the lounge but not the utility car. Similarly, the single level design needs three because there are total of three sleeper cars not counting the utility car.
Looks like they are considering three different options for Atlanta - Jacksonville:
Atlanta-Augusta-Savannah-Jacksonville
Atlanta-Macon-Savannah-Jacksonville
Atlanta-Macon-Jesup-Jacksonville
With the last one being used for the example route on page 110.
There was a thread here recently where the OP was in refreshed roomette. Managed to find it:

A feasibility study and a capacity study were done in the last few years. Both found on the I-20 Corridor Council website here:

So they shouldn't be starting from scratch, at least.
I would hope it'd be the cafe car going to New Orleans and they add the dining car back which will go to Dallas-Fort Worth, but heh, we'll see.
Taking a nod from the "adding frequency to LD services thread" I think they should also consider running the routes independently. Then there would be...
The Crescent, as currently travel between Atlanta and cities in South and North Carolina involves middle of the night departures and/or arrivals. Though the proposed Atlanta to Charlotte (or better yet, Raleigh) corridor would also fix that.
