I am not certain it is possible to go to other regions in Platinum, but I don't think they are accessible simply because you could do that it in the Emerald version. The only way (in my opinion) to get to the other regions are by using Action Replay cheats.
Mt. Coronet cannot be reached in Pokémon Emerald. It is not possible to visit regions outside of the version's main setting. It's especially impossible to visit locations or regions that haven't been created prior to a version's release.
No, Shuckle can't evlove in Emerald or any other version.
No. If you want to go to other regions you must buy other Pokemon games.
There isn't an eevee in Pokemon Emerald. If you go to serebii.net you can find lots of other way to get eevee in the other games
Red version was not made to migrate with emerald.
In Pokemon Emerald, it's impossible to leave the Hoenn Region. The Kanto, Johto, and Sinnoh Regions are inaccessible in Emerald. Sorry.
