The first problem I see is that mapping sidewalks as a separate way
should not be done unless there is a physical separation. For a
pedestrian the sidewalk is a part of the road. 

Mapping as separate ways can mess up routing for pedestrians who can
cross the road wherever they wish.

Mapping in the way you propose would leave the problem of where a
mapper would then place sufficient 'imaginary' crossings to not break
pedestrian routing
