If you're at all interested in doing the work, I'd personally LOVE to see a handful of these maps chronicling the spread of mankind's colonies through the Middle Heavens and the development of the political borders through the 22nd & 23rd centuries
Huge ask, I know, but just in case you're thinking about it, I would find that very useful when trying to wrap my brain around the in-game history.
The closest you will probably get to this is to take the Prometheus / Weyland timeline from the 2011 marketing campaign which lists colonies and dates and port those over to the Free League map.
Or maybe something like this:

A big inconsistency you will need to figure a workaround for is that some of the colonies listed on the map were *moved* from their real position in space to fit somewhere on the game map.
Most of the colonies labeled KOI (Kepler Object of Interest) are stars that exist far beyond the drawn map.
So all time/distance calculations get a handwave anyway.
Here's just a sample of the examples I found trying to correct the ALIEN RPG map for 3D plotting:
The colony, its ALIEN map coordinates, and then at the end of the line - the real distance to that star ... way off the map really.
Someone wanted those colony names from the Prometheus teaser marketing stuff to be present in the game so these (and others) replaced real star names or just dropped in.

So, with baked-in fudge factors like that - the best advice I can give on how to plot progressive colonization would be to calculate each colony's distance to Sol, and its current affiliation, and then run a timeline of "how many years divided by furthest colony distance" and then advance the timeline year by year and increasing distance from Sol and just make it a kind of spherical progression.
We do know that in 2122 Zeta II Reticuli and Thedus are both "way out there" and when Sevatapol and Acheron were laid down - so that gives you some milestones to know how much the sphere of expansion progresses over time.
