Crazy dry sump idea

Dry sumps - I had a crazy idea.

What if we replaced the current oil filter cartridge with one of those remote oil filter adapter that has 2 ports, an outlet and inlet.

We could take the outlet of this adapter and feed it to a big dry sump oil tank with air separators and whatever goes into that.

Then, we "somehow" drive a pump, that feeds the oil from the bottom of this dry sump tank, and feed it into the inlet port of the remote oil filter adapter, and send this new pressurized source of oil back into the engine.

The oil filter would be added somewhere in this chain, and it would be easy to add in an oil cooler as well.

The stock oil pump in the car would serve as the scavenge pump, and would pull the oil out of the current oil pan and send it to the dry sump oil tank via the remote oil filter adapter, with the defoaming etc... that occurs there.

I am sure I am missing a lot as there has to be more to it than that, but:

Pros:
  • Reuse the existing oil pump as a scavenge pump
  • The addition of the dry sump-ness would resolve the oil pressure drops during hi-G cornering

Cons:
  • Extra weight from adding the new dry sump components
  • All that extra pumping seems like it could change the vacuum inside the crankcase?
  • All of this would probably have to go in the trunk, but at least you could still store stuff in the front trunk

Sanity check:
If it was this easy, it seems like there would be a kit out there already. Why isn't there?
  • Room?
  • Weight?
  • Cost?
  • Other?
  • I have no idea what I am talking about and this post has so many issues it is impossible to respond to it...

All of the dry sump kits I have looked at for other cars seem to have all sorts of elaborate replacement oil pans, multiple scavenge pumps and deletion of stock oil pumps, many external lines to carry the oil along its journey.

The idea I propose above would eliminate many of these complexities. I wouldn't mind carry some extra weight if it would definitively resolve my oil pressure issues.

What is/are the fundamental things I am missing
