1. That map projection is not "from" that tv show. I get it, you saw it and thought it was profound. But the continued lack of use for that type of map is based on basic economic practices. The majority of global trade routes still follow north Atlantic routes and traditional Mercator projection just makes it easier to teach. Regardless, there's no need to shift the focus of our maps because the majority of groundshaking politico-economic interactions take place in highlighted regions like Europe and the US. As a prolific geographer, I certainly agree with the sentiment that the distorting of landmasses to justify a state's egoism is relatively disturbing. But everything has its purpose.
2. People don't want to play on maps that are unfamiliar. When an asshole wants to see earth, he expects earth to look the way an asshole sees it. And since the majority of territories on the WWIV map rely on the enlargement of the United States and Europe, editing it to fit your projections would make playing much more difficult for the tiny, out of the way Eurasian/North American powers.
3. All that being said, essentially, you'd want to have a map that fits the players. While the regular map is suitable for 90% of the players and 90% of the diplomacy that would occur, yes a map alternative would be a great visual aid for countries like Oceania, Australia, Philippines, etc. As mentioned, the coding would be exactly the same, so instead of asking for an additional variant, you could just add the map as a pop-up for the existing variant.
So yeah, I get your sentiments and I agree with you, but it's a lot of work for very little reward. You should just look into having abge or whoever's running that stuff now add the map as an alternative pop-up.
