I personally would rule out T-Rex, based on the sole reason that that they haven't built one yet and right now they theorize that it can push over 300 feet.
B&M typically does not make turns that tight on Giga's, and their footers are spaced out.
Mack builds close footers, just recently pushed over 200 feet.
Intamin can certainly does it an uses closer footers, starting to work their way back into SEAS.
S&S/Vekoma shouldn't be 100% ruled out.
A slight side note on the footers thing:
When submitting a plan like that, the box is going to be the entire effected area. Does not mean that's the actual size of the footers will be that big. When building in a buffer, it's not just the surface, but it's the sub surface and all the effected areas thanks to that construction.
