I assembled my own 10 speed by mixing 2 sets, 12-13-14-15-17-19-21-24-28-34

If I ever go to 11 speed, id probably do the same arrangement as my 10 speed but add a 16t.

Miche offers you the option to purchase your own selection of cogs for 10 and 11 speed cassette.

12 speed is too expensive and rare for touring, but if I did, then I might choose the same arrangement as what you've listed, as most 12 speed are on spiders and can't be mixed. Otherwise I'd swap the 11t for a 16t.

44/24 double chainrings

Edit:
Here's the Miche pimato K12, possible combinations

First position is either 11-12, 14-15, or 16-17. If you want 12-13, I would imagine that you could look for spare Shimano 12-13 and lockring.

Edit 2:
Seems Shimano does not have a 12t first position on their 12 speed cassette. If you have a hyper glide freehub, maybe it's possible to take the 12-13 from an 11 speed, although the pitch will be off by maybe 0.3-0.4mm, possibly negligible.
