Currently the 5 destinations available are:

-Disneyland Paris / Marne La Vallee
-Calais Frethun
-Aime-la-plagne (winter only)
-Bourg-st-maurice (winter only)
-
Moûtiers (winter only)
-Marseille (summer only)
-Lyon (summer only)
-Avignon (summer only)
-Aix-en-Provence (summer only)
If we take the doubling to mean going from 5 to 10 direct destinations, that could be achieved if the direct summer/winter seasonal services both restarted. Of course, new destinations may also happen.
The main point of those facilities is that there are platforms that can be isolated from the rest of the station, which is much harder at many other stations. No-one is pretending that no work, not least an agreement with the Swiss government, would be needed.
While certainly not everyone would switch, Geneva is one of the more realistic options, compared to many that get suggested. That doesn't mean it is easy. However, speed is not the only thing people take into consideration when arranging travel, and eurostar could compete on both sustainability and comfort at the very least.
you could stop in Lille, without extra work. Potentially, stopping at Disneyland Paris, or (some of) the former ski eurostar destinations would also be possible, but would require extra work.
EDIT: just looked at a map and realised that the former eurostar ski destinations aren't actually on the route to Geneva, so stopping at them isn't possible. Geneva and surroundings are potentially a spot for ski holidays itself obviously
I agree this is a fair criticism. Though I'd say losing the infrequent seasonal services for the 4tpd Amsterdam/Rotterdam service may have been a fair trade, and is likely getting more passengers than the seasonal services did.
Wouldn't these serve Basel SNCF rather than Basel SBB?
Overall, I'd say I hope they succeed in getting more destinations, but I'm not holding my breath!
