A fan-made map would make the perfect setting for a hypothetical Red Dead Redemption 3, even if it leaves out iconic locations from the two previous games. Of course, no one knows anything about Red Dead 3 at this point in time, but it is believed to be in development at Rockstar. Whatever it turns out to be, it'll have to differ significantly from the previous two games. Since RDR1 and 2 have basically taken the van der Linde-Morgan-Marston saga as far as it'll go, RDR3 will have to go elsewhere for inspiration.
