WI Georgia kept by the British after the Revolutionary war?

I have at times considered writing something along these lines, but primarily held back by virtue of knowing fairly little of the minutiae of the ARW. I had considered the angle of the black loyalists: If they are settled primarily in Georgia instead of scattered about in the Carribean, Canada and the UK, they might form a significant population bloc in and of themselves (the population of Georgia after the ARW was just over 80000, while there were tens of thousands of slaves freed by both sides with promises of freedom. Thus, when Britain starts to blockade slave trade and abolishes slavery in the British Isles, Georgia might well also have an abolitionist plurality if not majority (probably very much depending on if some of the poorer white population goes along with it), which would lead to interesting things.

Physically separated from Canada, Georgia would be a separate colony/province with a separate legal system. The heraldry is easy as well, assuming anyone of the loyalists knows enough about history to know the flag of the kingdom of Georgia (which disintegrated in 1490) to incorporate it, which I find very possible. Depending on how one looks at it, it'd be either the White Ensign with small crosses in three corners or the historic flag of Georgia with the Union Flag in the canton. Georgia might possibly end up in control of some of the British Caribbean possessions eventually.
 
A few more points.

There is a key difference between the British just getting Georgia at the Paris peace conference, or getting East Florida as well. IOTL the Spanish held West Florida by right of conquest but not East Florida, which was thrown in because it was not that valuable. This is where the POD of the British holding Georgia because their military situation is better in 1782, as opposed to Georgia not siding with the Patriot faction in the first place, makes a big difference. Also, if the military situation is not changed, if the Spanish don't get Florida they will likely get concessions to make up for that in other areas, with attendant butterflies, for example one of the minor concessions could be the formal abandonment by Britain of the claims it had just started to make on the Falklands.

The biggest difference in the two scenarios is that twentieth century American "Florida" gets butterflied away, which as big repercussions affecting just about everything. There is still likely to be a state of "Florida" on the Gulf coast east of New Orleans. But also there is the strategic depth to form an independent dominion out of Georgia, East Florida, and the Bahamas, though I'm not sure what this country would be called. This is not the case with Georgia by itself, which winds up as a de factor protectorate of either the UK or the US.

The USA never got its hands on any additional British territory, other than that involve din settling boundary disputes, after 1783 IOTL and I don't see why it would ITTL. So if the British get more in the Paris peace conference, they likely well keep it within the empire and the commonwealth. An analogous situation is if the British wound up with what is now the state of Maine at Paris, I don't see any big irredentist among Americans, especially in the timeline where Georgia never participates in the continental congresses, and the major difference is that a major city developed in Georgia IOTL but not in Maine.

Another point that people seem to be missing is that OTL Atlanta probably does not exist. It developed as a railway hub because geographically you have to rout railways around the southern portion of the Appalachian mountains. You really don't want to run rail over the Smokey Mountains between North Carolina and Tennessee, though I suppose its feasible to run a rout through the Cumberland Gap further north. Doing this ITTL means crossing an international frontier twice. There will still be rail traffic on that rout, sort of on the lines of the routs in southern Ontario, but less than OTL and hence Atlanta never develops into a major city.
