It is a big area when you look at that picture. Definitely some possibilities but I suppose this is down the pecking order.Ideally if we never got Galactica in 2016 and Towers still had some more money to play with or if the incident never happened, it would have been nice if they had gone to really expand that area around the attraction to make it is own thing as when you look as the area around it when you don't include the car park behind the ride, its a fairly sizeable area to play with as you can see from this image of the area.
The queue lines themselves are just wooden fences, cattle pens in truth, with nothing to them so you could easily not only reroute them but theme them into the attraction far better, imagine walking past many relaxing waterfalls giving a calming feel about it. In doing so you open up more of the area in which instead of converting the Air shop, RCR could have had its own building in that area by the final turn on the ride and could have given you a good view of the ride and of a wider themed area that would have been Forbidden Valley before Nemesis corrupted the land in which you could say the area was called Thunder Valley before (a wink to the area's past name before) or something not dark in which the Stonehenge theming idea of worshipping Nemesis as we see in FV could be used here. A more 'lighter' theme would really help balance out not just FV next door but pretty much all the other dark areas on the park.
I agree that if you had a Ripsaw replacement on its original location then you could split FV in two as with Blade, Nemesis and Sub Terra being there then the area would be more or less up to full strength. With this new area, you could have another flat ride or two in that area or even a indoor Valhalla water ride on the site of the car park but I digress. Either way, it is an possible untapped area of the park that could be put to good use and not just hidden away from many other than those in the queue for Galactica. Either with my proposal or maybe just include it into the wider Phalanx theme means its ripe for change either way.
One reservation of the car park area would be how far any new ride / area would be from the park entrance. Galactica is a hike as it is.
Either way though getting the ride back nicely presented is a must. Really enjoy the ride.
