In one of the latter Shackled City adventures, there is a side-bar for approximating monsters that are in the FF with standard MM critters (I can't remember any particular examples, but they were on along the lines of "Demodand = 12th lvl Gnoll Barbarian" etc..). It made me wonder whether an article tieing up a bunch of these kind of questions could make it into Dungeon - I don't know much about either Eberon or Forgotten Realms, but an article that ran something like:
(FR god name) is the god of healing and mercy in the Realms - in an Eberon campaign, replace this god with (Eberon god name), in Greyhawk, use (WoG god name).
Drowe are a common adversary in Forgotten Realms, in Greyhawk, replace the average Drowe with 2nd lvl Hobgoblin Fighters with the (whatever) feat, in Eberon use (whatever).
You could touch on all the major setting elements of each campaign and suggest equivalents, races, dieties, specialist feats, specific artifacts etc ... in cases where a direct port was possible, suggest ways to make the imported thing fit the flavour of each campaign. You could have a side-bar listing equivalent places in each realm too, so that if a Greyhawk adventure is set in say the Barrens, where roughly equivalent places exist in the Realms and in Eberon.
I'd write the article myself, but I'd need a bunch of books to do the research ;-)
Do you think it has any mileage/appeal?

I think that's a great idea, like the setting-specific blurbs in the Monster Manual III. Drow are originally from Greyhawk, though, so there's certainly no problem using them there.
As I understand it (and I probably don't), Drowe hang around all over the place picking fights and looking cool in FR, where as they kinda skulk in the shadows manipulating things in GreyHawk ...
