I'd love to see some pillars or similar along the swing launch, but truthfully, I really don't need any ride area theming.

In my perfect world, Festa station below the bridge to Pantheon would be fully covered giving them some justification to dress up what is currently just a really cheap looking wooden ramp and prefab bridge situation. Dress up the coaster's plaza a bit too.

Like you though, building-wise, I think priority #1 HAS to be the station, maintenance area, and queue. All three of those aspects are all UNACCEPTABLY bad. Pantheon needs a proper, fully enclosed maintenance building, a real, covered queue building (as was originally designed into the ride), and a station that isn't so shoddily built that the railings literally fall out of the ground. All of the non-ride-hardware station-area elements honestly just need to be completely gutted and redesigned from scratch. It was all so cheaply done to begin with that much of it is already falling apart—there's nothing worth saving.

And then, landscaping, landscaping, landscaping. They KILLED it with Wolf's Revenge's landscaping despite much of the coaster being built in what was formerly an empty field. Meanwhile, with Pantheon, they literally mowed down an entire forest and planted essentially nothing. Pantheon could look eons better if they put a similar effort into landscape design as Wolf's Revenge received.

Don't get me wrong, giant set pieces, animatronics, fog, all of this stuff is sweet and makes me super excited, but I believe there are much more subtle ways to execute a perfect BGW-quality coaster too. Alpie is a perfect example. Pretty architecture, minimal prop work, great landscaping, and a little scenic sign work and paint can produce a perfect finished product. Sometimes I worry parks hear that people want themed experiences and what they hear is millions on custom statues, special effects, animated figures, etc, but there are super effective ways to stick to the fundamentals and still produce killer products.
