It's not impossible - but the devil is, as always, in the details. You 
can obviously limit it to only cases where there is a motorway with a 
motorway_link branching off and no left/right tags, but it's not just that.

If that link itself then has a Y branch (e.g. to turn left or right), it 
will need splitting because it's unlikely both branches will lead to the 
same place. There are probably other cases.

If there is a desire to do a mechanical edit I can probably take a look 
at doing so and we can hash out the logic required, but I wouldn't want 
to do so until there's general agreement on the idea in principle of 
doing a mechanical edit.
