turrets have increased resistances if no enemy minions are around. i guess technically that could work. but he would be very slow, as he would deal very little damage with each individual hit.
he also cant get many q's launched off until his e runs out. usually 3 maybe 4 missiles with cdr.
but he would be really good in siege scenarios.
With a Last whisper and his E armor shred (If it worked on turrets I'd assume the shred would) those resistances would be a lot weaker, allowing him to split push a bit more effectively. But what would be really insane, would be that not only would he be able to clear turrets from over a wall but minions as well. He can already clear minions from the other side of a wall, but with a tower pushing buff he could get waves to your turrets without showing up on the map.
It'd force more wards in inconvenient areas, as there would have to be wards to prevent him from tower pushing from the wall. This would increase gankability, decrease the power of anti-siege, and increase the ease of counterjungling as choke points would have less wards available to be used until level 9
Edit:
If he did 200 damage per Q to turret after buying last whisper and max CDR, he'd be able to do around 800 damage every 8 seconds (Not counting E damage) to a turret without showing up on the map unless the majority of the map and not the objectives was warded. So, in around 24 seconds he'd be able to take a turret in the mid-lategame without showing up on the radar.
