Yes it would be the most free flowing, and this setup is used (or atleast shorter pipes) on turbo setups, Where they run the intake directly into the turbo with very short piping.
As for putting a cone directly onto the TB, it wouldn't work as good as having a tube connected to your TB. The tube is not only to extend the reach of intake, but to create vaccuum pressure required by the Naturally Aspirated engine.
On Forced Induced engines, The engine works opposite to that of a naturally aspirated engine, in which it Blows (forces) air into the combustion chamber when the intake valves open.
In a Naturally Aspirated engine, the engine "suck" of the piston going down and the atmospheric differences (in pressure) of the combustion chamber and the intake draws the air neccesary to go boom. When the intake valves open, air is sucked in.
Now, in regards to the Tube/cone idea. When you have just a cone, air is being sucked in but it will not be as strong as it could be. When we add a tube to create a vacuum (A space in which the pressure is significantly lower than atmospheric pressure). So when the valves open up again, and the engine wants air, the atmospheric differences between the chamber and the intake takes effect and air is sucked into the chamber due to the differences of high and low pressures (like the weather).
Get it?
If you just have a cone, you don't get a strong enough vacuum created, and therefore air is harder to be sucked in, because the differences aren't as great. And most cars won't operate without the sensor connected, nor with the engine not having enough air to breathe on.
Thats why, when naturally aspirated draggers run at different locations, they always have to check atmospheric pressure at the track, so they can compensate their engine to maximize on the difference.
When people use carbs(racers), they have to constantly adjust for optimization because they have no air flow sensor to compensate to the differences in pressure, unlike EFI's and all their sensors everywhere.
forgot to add this, if you see domestic dragracers whom are n/a, they get a hoodscoop, and turn it towards the windshield. They do this because air goes over the hood, hits the windshield and goes over the car right? But that reversed hoodscoop maximizes on the vacuum pressure created by the air flowing over the hole..
