I live in Piemonte, very close to all these climbs. I climbed all of them multiple times, from all possible sides.
Trust me...this stage profile is absolutely nuts.
On a serious note, I do not see any possibility of a stage with the Fauniera in the next few years. I have been on the Fauniera a couple of times this summer...
- The side of Demonte has sections with a very rough tarmac, and the descent in general is very dangerous. I do not think that Mauro Vegni would choose such a dangerous and difficult descent.
- The side of Castelmagno is a bit better, but the quality of the tarmac is still way worse than what you find in France, for example.
- The side of Ponte Marmora is just awful, it is absolutely impossible for a professional race to use that side as a descent, as in the stage profile above. It is the best side of the Fauniera in terms of landscape, panorama, and views...but the road is just way too narrow, full of cracks and potholes.
The same holds for the Sampeyre. Elva side officially clodes because of rocks falling down from the right side of the mountain. Stroppo's side needs to be fixed in many places because of poor tarmac...same thing for Sampeyre's side.
Lombarda and Agnello do not have such problems...but they force you to go into France, meaning that it is not always possible to plan a stage there.
However, the Granfondo Fausto Coppi has been canceled for 2022. I have no idea about the reason...but what if the organizers decided to invest the money on a stage of the Giro instead of the traditional Granfondo? I am purely speculating...but I would love that.
