For visualization, refer to Gardiner Expressway over Lakeshore Boulevard in Downtown Toronto.
This way, we only need to relocate 1-2 properties instead of everything on the east side. Aesthetics will be one of the problems though.
Edit: Never mind that's a dumb idea.
At this rate, crossing Trout Lake and then squeezing in between the golf course and the airport may be the only viable option. :/ And that's only for the 11. For 17, we will need to come down east of Nipissing University (with an interchange to access it) and go down Gormanville Road to merge back to 17W. Hence, everything along that road will have to be relocated onto College Drive.

If you look at Google Maps satellite view, you will see that most of the land is clear from where 11S and 17E interchange to almost O'brian. That takes care of that area. It i from O'brian to the top of the hill that is the issue.
I still think they will swing 11N along the edge of the FN reserve and the Duchesney Falls/creek area. The West side of the falls have only a trail that follows the river. Also, that land is not a rugged as trying to tame Thebault Hill.
To tame Thebault Hill:
1) All businesses along Algonquin North of 17 would need to be removed.
2) A berm or overpass could be built that would reduce the grade and make the transfer to 11/17 reasonable. It would also allow the installation of an interchange with McKeown/Airport Road.
.....
There are many challenges to twining.
For another example, look at Blind River/Algoma Mills area.
You would need to put it north of Lake Lauzon.
