Two Inline Fuel Pumps
There have been quite a few threads on fuel lately, so why not one more 
Is there anyone who has removed the intake pump setup and replaced with a pickup and bulkhead fitting that has two 255 inline pumps as feed then run a FPR and return back to the tank?
It is a proven setup on other high hp cars. Why would this not work on a C5 as well?

Do you mean two inline pumps run in serial, or two inline pumps run in parallel?
I think the APS fuel kit runs two inline pumps in parallel. And for what it's worth, the ECS fuel kit can run the same way, you just have to plumb it differently. When I bought my kit it even came with enough hose that I didn't have to buy extra to run mine in parallel.
Oh, and I wouldn't just remove or disable the OEM system. It runs the tank to tank transfer venturi pump. If you come up with an alternate method of moving fuel between tanks, make sure that the passenger side drains first or you'll get a CEL code that will cause your gas gauge to show the car is empty. The PCM expects to see the passenger tank with less fuel than the driver tank or it thinks that the in tank fuel level senders are busted.

I assumed that by your description (twin pumps running through a bulkhead fitting) that meant you were going to plumb AN -- likely #8 or bigger -- and bypass the OEM stuff. No matter how you do it, just make sure the OEM feed lines are seeing pressure or you'll interrupt the tank to tank transfer mechanism.
