All right, so it is impossible to put arena and daggerfall into skyrim, I get it.But would I be possible to Put battlespire in the skyrim engine. If not how about Oblivion and Morrowind Engines.
I that is not possible how about using Redguard to make Skyguard of MorroGuard or ObliviGuard?

Likely not. Morrowind and Oblivion both use the Gamebryo engine, and Skyrim's Creation Engine is based on an improved Gamebryo. Morrowind, Oblivion, and Skyrim have similar formatting. This cannot be said for Battlespire or Redguard.
