Ill throw this out there as I just replaced the black tank in our 77 rear dry bath Royale this spring.
Two things to consider is where the bathroom is located, as well as if its a GMC or a Transmode as it makes a difference, (and would possibly make a difference on any type of production run numbers for a new tank).
Our Rear Dry Bath has a dedicated 19 gallon black tank. The only thing that fills that tank is the toilet. The Toilet cut out is basically right over the RV outlet on the black tank.
All the other water sources fill the 35 gallon grey tank, just forward of the black tank. Kitchen Sink, shower/tub and bathroom sink. This has worked out for our limited camping thus far just fine.
The rear bath layout of this makes it possible to not have S*&$ roll up hill to get in the tank and also makes dumping a bit easier with a slight incline or drop in pressure of the air bags. My set up (Similar to Mr. Hupy) allows me to dump the grey as often as needed without touching the black. Not so in a true GMC with one common tank for everything.
Thats just something to think about.
The issue is not so much the space to put a bigger tank underneath. The tricky part is possibly re routing all the outlet plumbing to get to the tanks with enough slope to drain into the tank properly when the coach is level or close to level.
