Remember, the reason we experience what we call 'gravitational lensing' is through observation. If you are standing on an object of significant cosmic inertia (massive), you would perceive the same result as if there were some 'mysterious force'.
An object's relative velocity only really affects the time it spends in a given portion of space. Keep that in mind for a few moments while I explain what's really happening:
Let's say there is an object above the planet. The Earth is accelerating toward that object at a rate dictated by the effect of the cosmological constant compounded by the mass of the Earth. By this very same rule, the CC works on space as well. Therefore the space between the Earth and the object is also 'expanding' by the rules of the constant. Now, since all things are 'relative', and the space between the object and all points of the universe are expanding by the same constant, that object may remain 'stationary' until acted upon by a force. So, at a certain point, since the object is NEO, if the space between the Earth and the object is reduced to the point where the acceleration/inertia of the planet supersedes the expansion of that space, the object begins to "Fall". As the acceleration of the Earth reduced the space between it and the object, the space would have less and less of an 'anti-gravitational' force and the Earth would 'gain' on the object with ever greater velocity.
It is exactly this 'reduction in space' caused not by the mysterious 'force of gravity' but simply by the actual acceleration of the Earth which makes anything, including light, subject to being observed as 'falling'. What is actually happening is that when something passes through that envelope where the acceleration of the planet exceeds the separating potential of the space between, the Earth, by virtue of it's acceleration, 'sheds' the space between. Since light travels so fast, it is obviously less susceptible to be intersected by the accelerating mass simply because it's not at that point for quite as long, but we still see the reduction in space between the massive object and the beam of light.
IOW: Everything would appear exactly the same.
