My personal aspiration has declined so vastly. I'm fine with Stelvio - Bormio 2000.
It's realistic. Stelvio was strongly rumored for 2025. It means Stelvio would be ridden from the hard Prad am Stilfsersjoch side. Bormio 2000 is a nice average mtf to make long-range attacks stick. The ski station could potentially pay for it. Most important both Stelvio & Bormio get constantly cleared with a snowplow so the stage actually takes place.
Finestre will be at the Tour de France for its 20 years anniversary. That's what they pay for.
Everything else. Kronplatz / Corones, Würzjoch / Erbe, Jaufenpass / Giovo, Fauniera, Gavia. It's nice dreams but not happening.
Only Manghen - Alpe di Pampeago sounds like a good and realistic idea. Then again, Reiterjoch MTF from the South Tyrolian side would be better...
