About VistaVision

Okay folks, hear me out. Considering VistaVision 8/35 is to 35 mm what IMAX 15/70 is to 70 mm, which is an alternate usage of the same film stock running horizontally instead of vertically, can VistaVision be used as a cheaper alternative to shoot movies for IMAX ?

I've just seen the trailer for One Battle After Another and it was shot in VistaVision and should be exploited in IMAX this year and I find it absolutely amazing.
