This sounds very interesting...
As mentioned earlier, the southern area with the old factory might also be a possible place, but I guess Balder and Kanonen make up quite a "wall" at that side of the park. Any paths going there would be a little off the beaten track, and get clogged with people every day the sun shines.
Then, on the other hand, aren't there an awful lot of neighbours just past the top of the mountain? The only place I can see where noise wouldn't be an issue would be the gardens, with the Universeum being the only neighbour to that part of the park (and that is big and soundproof). But I can't really see them build anything in the gardens (not to mention that it would clog up the entrance; parks want people to go as far in as possible).
Liseberg needs a few more inversions, an Invert would be well suited. If they could build it so it interacted somewhat with Lisebergbanan, it would be awesome.
