Tremalzo isn't that far from being raceable compared to many.
Cà San Marco from the south then a descent finish in Morbegno, per favore. And a tough mountain stage in mid-altitude around Sanremo. And two Valdostan stages. Clone that Torgnon MTF stage from a few years ago in the GDVDA, or maybe a Pila MTF (after Lin Noir?), if it has to be such. Way better final climbs than Cervinia. If MTF is not a necessity, then Aosta descending from Lin Noir after a bunch of climbs would be immense.
Tze Core - Saint Pantaléon from Châtillon - either Champremier or Saint-Bartélemy - [Pila-Les Fleurs?] - Lin Noir - descent finish in Aosta would be absolutely ideal. If it's decided to be too much, can always replace Tze Core (*sob*) with Arlaz. Other options would be to finish at Pré-St-Didier, Morgex or La Thuile after Colle San Carlo (so Verrogne instead of Lin Noir then San Carlo). Even better, perhaps, a short punchy uphill finish in Courmayeur (which is a pretty well known ski town and has money) after San Carlo's descent. Alternatively, the ski facilities at Brusson could host a finish after Tze Core - (Saint Pantaléon from Chambave) - Joux from Châtillon with a very short descent (like the La Thuile stage in 2006).
Rucas MTT from Pinerolo
Monte Matajur (after Madonnina del Domm and Passo Glevizza with a route that doubles back on itself possibly?) is something that we do need to see one day.
...and FEDAIA. FEDAIA FEDAIA FEDAIA. IT HAS BEEN FOUR FEDAIA-LESS YEARS AND THIS IS TOO MANY.
