Nope, sorry, doesn't work. Not up to date. it would have looked terrible in the context of this. It's the 21st century. IO'm not saying go hogwild with CG, use it wisley, and as I said, it could have been used more wisely in the finale in the fourth film.
Like I said, if the first three Indy films were made today, the scene with the powers of God coming out of the Ark would have been CG no doubt. People getting electrocuted? Heads exploding? Faces melting? The prosthetics would be better or they would use a different means to achieve the effect. It's the evolution of special effects. They evolve over the years. If LC was made in 1981, the scene where Donovan transforms would have been done differently. You don't use the techology you had 10 years ago. You use the latest kind. Like any special effect during any time period.
The shot where Mola Ram falls off the cliffside and into the river could not have been done in '81. New technology.
