The front half of the park is much flatter than the back - there are some choices that would not only be at least as flat as the area it's in at SFA but possibly even flatter (SFA is less flat than Darien Lake). And the Tidal Wave location has variations in elevation along any potential orientation but the overall elevation from station to turnaround wouldn't be drastically different heading forwards because there's a mound in the particular location by Batman, tall footers would cover the low points. I'm still not sure they want to spend relocation money either but scrapping coasters isn't free - there's a chance you could be unhappy for at least someone in the chain. It still costs several million dollars to scrap these things.
