I think the story should NOT revolve around politics of the 50's/60's because the Russians are just not that interesting as bad guys. I could be wrong, but let's face it: Nazi's are universally accepted as the guys you love to hate and it would be tough to capture the same dynamic in a different political advasary. I think instead it should be removed like Temple of Doom was. And as far as Indy's kid, guy or girl, I think it would be a mistake. Do we really need more characters? Instead I think they should reintroduce Shorty and Willie Scott -- Now just hear me out... Remember Wu Han in the beginning of Temple of Doom? Well, I feel like that's what Short Round should be -- like Sallah of sorts. And Willie I see as running a night club but now she's a woman with connections and can get certain information. Just my $0.02 worth.
