One can do anything with enough money, so I won't chase down a rabbit hole over whether a heavy rail line is technically possible alongside (rather than down the middle of) the 407. (But the junction at Langstaff would be very tight.).
I wonder, however, if the ridership would make this investment worthwhile, especially with TTC Line 1 also heading towards Richmond Hill.
There are two other logistical issues I see - one, to upgrade the Richmond Hill service to 2WAD and impose this on the Barrie Line might not be possible - it effectively doubles the volume of trains on the Barrie line south of the 407. And two, CN's willingness to accept a 2-track electrified line from Langstaff northwards is doubtful and difficult to accomplish. Freight trains also travel on the north to east leg of the Doncaster Junction - meaning CN needs access to both the west and east sides of this corridor. Accommodating rush hour diesel trains is doable, but CN is extremely reluctant to have its trains use or even cross an electrified route at any point.
Then, there is the question of how to serve Oriole and Old Cummer stations. Withdrawing service from these catchment areas would be problemmatic. And I don't see much potential for transit oriented development along the 407 without adding new stops (and hence adding to trip time) - whereas Leslie/Finch might be able to absorb a little densification..
The better answer might be to reroute the Richmond Hill line down the former Leaside spur. The NIMBY potential of that route is so high that I wonder if it's even possible. But even if trenched, and including a flyunder under the CP at Leaside and under the CN at Doncaster it would likely cost less and offer the same improvement in trip time as the proposed jog along the 407
