A game like that would just retcon the crap out of everything, as if Konami did make a game on the FE, they'd include something similar to the iDroid, probably something similar to Drebin for the many people who loved him, which would break the story of 4.

Really for any Metal Gear game to be made, it has to be an alternate universe/alternate sequel akin to Ghost Babel, or the Ac!d series.
