Gen-III valley cover onGen-IV engine

I don't have a Gen-III valley cover in-hand to play with, but I am assuming it won't fit a Gen-IV engine because of the AFM/DoD risers in the Gen-IV engines' valley?
I have an LS7 that I want to put into a '99 truck which currently has a 5.3L.
I know that some people have relocated the LS1 knock sensors to the side of the block by drilling, tapping and extending the harness, but I don't trust sensors tuned for the valley cover to work on the side of the block. And I most definitely do want to retain the sensors.
The risers in the LS7 block's valley have not been drilled. So I'm wondering, can I simply have these milled out so that I can use the Gen-III valley cover, keeping the knock sensors in their original location?
This LS7 already has a 24x reluctor, and wet sump oiling. The knock sensors are my only hold up.

I have read that using the Gen-III sensors on the side of the block doesn't work, or doesn't work very well. I can believe it given that they are designed to be placed elsewhere. But it seems like it's either that, or don't use them at all.
Thanks for the reply, it was very informative!

We've done over a hundred swaps of Gen IV into Gen III cars. We've always used the knock sensor extension harnesses and relocated them to the sides of the block. Based on actual testing with the knock sensors in both locations I've seen no detrimental effects with relocating them. They do register knock very well on the outboard locations.
Thanks,

Just to be clear, the "new style" knock sensors mentioned above will NOT work with an early style 24X computer. You must use the knock sensors which originally came with your car/computer.
