Even if you somehow pulled a vacuum in the tunnel (very dangerous) you'd still be falling at whatever the terminal velocity of the friction of the retention mechanism of the box in the hole results in (which will be less than freefall).
The only way would be to add acceleration to the box via whatever it's mounted to.
If you wanted to do this for say 2000m you'll end up at the speed of sound or more.
And it'd last for about 20 seconds.
So you'll get the experience of the vomit comet for about the cost of a Falcon 9.

Oh man, really? I mean 20 seconds would be neat, but I don't know if you could find a 2000m mountain. Like, Ha Ling is 800m from valley floor to peak, I think.
Also, I don't understand the rest of what you said, but I trust that you know what you're talking about. Sounds like I wouldn't be floating inside the box?
