I agree with you in a sense but we must remember that while Indy may have the secret of eternal life Ford does not, therefore as far as i am concerned the whole grail episode is pretty irrelevant WHILE Ford plays Indy.
However the grail seems to me to be a comic book mechanicism of giving a character eternal youth and it could be used to set adventures in the present day however horrible that would be and it would take him out of the 1930's.
But as i say that is i hope never going to come to fruition
I think that Lucas did not really care much about the consequences of the grail as LC was supposed to be the final Indy film and he only threw in some dialouge that didnt make sense ('the price of immortality etc') and left it ambigious, so there can be no final answer.
It must come down to Not proven in the deeper sense and a simple No in the simple sense.
