Best method of making dual scoops functional?

So I have heard this story from multiple sources over the years:

Dodge wanted to have a real cold air hood for the 340 Dart in 1970. The idea was to use an air cleaner without snorkles that would be fitted with a plastic insert that would go out, have a 90 degree bend upward and a foam seal that the hood would close on. The air cleaner got designed and the hood with 2 scoops and holes in the right place just in front of the air cleaner holes, but something went wrong and they ran out of time so the connecting piece never made it to production. I have never seen any documentation that would back up the story.

When you look at it, I am surprised that nobody ever made a set of 90 degree pieces to connect the factory hood holes to the 70-1 air cleaner.
