I believe the ultimate route network in the area is greatly different than it is now:
1 would follow Stoney Trail SW and S, then 22X onto a new extension between Carseland and Strathmore, rejoining the existing route north of Gleichen.

The province has shown some documentation of the 22X/901 freeway; however, the issue would be that the TransCanada Highway would significantly bypass Calgary. Alberta Transportation has a study online that twins Hwy 560 (Glenmore Trail) between Stoney Trail and Langdon. My though has been that if this extended east and tied into the current TransCanada Hwy, TCH 1 could run along Glenmore Trail (the city is slowly making it freeflow) and then rejoin 16 Ave using either the west Stoney Trail or Sarcee Trail. This would result in TCH 1 still passing through (instead of around) Calgary. Dangerous Goods that are prohibited on the causeway could use Stoney Trail.

The orphaned TCH, including the 16th Avenue section, would likely become 1A, at least from Deerfoot Trail to Strathmore, including a new SW bypass and connector. Existing 1A along 17th Avenue SE would probably be decommissioned, although a secondary number might also be warranted.

Now that Chestermere and Calgary adjoin each other, the current Hwy 1A east is entirely under either City of Calgary (17 Ave SE) or City of Chestermere (Chestermere Blvd) jurisdiction. New signs at TCH 1/Chestermere Blvd no longer show Hwy 1A and I contacted Alberta Transportation and they indicated it’s no longer a provincial highway. In short, it sounds like Hwy 1A has been decommissioned and they just have to remove reference signs in Calgary.

21 would likely be extended south to Carseland via the SE Strathmore bypass, then along 817 to meet 24. One plan has 24 being used on that section, but that orphans a section to the west through Cheadle, so I wouldn't change 24 personally.
22X would only exist as far as the Stoney Trail SW bend. East of there, it would be 1 (and 201 on the Stoney Trail portions), with an extension to meet the 1A connector described above near Namaka.

I'm wondering if it could be renumbered to Hwy 66?

Most likely, 201 would run concurrent with 1 on Stoney Trail SW and S to keep things consistent for through traffic.
560 is important enough IMO that it should just take on the Highway 8 designation as a primary, and extend it to Highway 24 south of Cheadle.
567 (E-W portion) and 840 (N-S portion) are the most logical designations for the orphaned TCH between Strathmore and Gleichen. Given that traffic volumes would fall off a cliff as a result, two lanes could be graded out and the 567-840 intersection realigned so that they are local access highways and not looking like an expressway.
817 would be shortened to start in the southern edge of Strathmore at an interchange with 1A/21 as a result.
901 would likely take on a new secondary number (most logical would be 554?) as it would never be part of Highway 1 through Siksika so the temporary number would not be useful. Heck, I would just renumber it as 554 now.
A couple other things I would do, that are not planned at this time:
9 should be realigned to meet Stoney Trail NE at the bend north of Country Hills Boulevard, running on a new alignment to Kathryn/Keoma, for quicker and simpler access from the northeast (as far as Saskatoon). It probably only needs to be 2 lanes at this time, but protection for a wider corridor should be made.
797 would pick up the north-south section of 9, as it is a straight linear extension.

I'm wondering if Hwys 583/806/9/797 could form a new highway between Three Hills and Langdon? Maybe Hwy 30 (I think its unused).

Do you know if the province has done any studies of AB highway 9 ?

There are old documents that propose Hwy 9 following Hwy 564 (Country Hills Blvd) into Calgary. Too bad it never came into being.
