I feel like this topic has been done before. The reason nobody has made any FPSs in that era is that there is exactly 0 variety in the weapons, not to mention that they would be incredibly inaccurate and take forever to reload. The maps would mostly be the same, as they would usually be varieties on "open field #3".
In short, any shooter made in that era would be boring and repetitive, and not very fun. Good story concept does not equal good game concept.
I gotta say, I disagree. I think the lack of variety in weapons, reloading times and maps are all trivial things, that with good story telling and design ideas, can be easily overcome.
You could just make the player-character reload faster, think up weapons that are not the standard pistol, shotgun, machinegun fare. And the maps? There are many places/buildings you could choose to set a game level in that era rather than a field.
I think even with a slightly open mind the kind of 'limitations' you are talking about could actually inspire some serious creative thinking and potentially, with the right team behind it, a really great game.
