I would like another big climb in Watopia. But at this point any expansion to Watopia would be nice.
When I look @ the Watopia map, it seems the coast around L’Alpe du Zwift is low-hanging fruit. There could be a coast ride similar to Milan San Remo, for example, with the coast route, or various inland climbs. At present long rides tend to be convoluted, and this would provide a longer excursion option.
They could add Cipressa, Poggio, and additionally another long climb up the backside of the mountain. Anything with around 1000-1200 meter elevation change could be made to work. Monte Zoncolan?
