yes, orange islands was a filler saga (and one of the most interesting sagas btw) but it could happen on the games eventually, its not written in stone that it'll never happen...Game Freak might pull a fast one one day and say "oh here Pokemon Orange"...hey maybe not too likely but it
could happen.

As far as I know, it is said that this game will take place only in one Region and old Regions will not be in this game.
They said that about Hoenn, they haven't said much about Shinou so you definately need a link since i haven't heard anything about that.
i'm pretty sure it IS not confirmed unless someone can post a link.

why on earth would you want to go to regions you've already been to?
if you want to be in old regions, play the games that feature them.
Simple as that.
same thing could be said about the FR/LG remakes you could have just played R/B..and just made those Pokemon available only from Colosseum/XD

As far as the actual thread that would be a neat way to do it and a very interesting theory, however:
I am not too familiar on how the DS gba slot works but from what I know i don't think the DS can read a game from both slots the way you are posting it could work.
If it could read the data the way you explain it (which like i said i don't think it can), it would still need to actually be programmed to D/P since the graphics engine is different anyways, maybe only being unlockable if you put the older cartridges but not actually reading the cartridges.
However the releasing the older Pokes in the wild in Shinou can be done, it would be very similar to Pokemon Dash on the DS that gives you new tracks with the different Generation III games, since it is just recognizing you have the games.
