Bethesda would never even think about such a thing so your only choice is getting someone to make a fan-based mod.

Go to http://forums.bethsoft.com/ and pick which elder scrolls game you want. Each one has a section for mods.

I do understand that you have addressed the notion itself, thanks for the response btw. I fully expect game creators to be tough nuts to crack with this. That said, I have faith in the strength of the storyline and faith in the fanbase for both games. From a purely economic sense, Bungie, would lose few if any of of it's fans while gaining the substantial Bethesda fanbase and Bethesda would gain Bungie's. One would think that any suggestions to a game developer that includes a realistic expectation of strong sales increase would be worth a little of someone's time.

Why would they make one game for half profit when they could do one of their own design for full profit.

Could be nail in the coffin for my notion. Damn! I guess I'll be rethinking my idea. A damn shame because I firmly feel the storyline fits well and would be considered "epic" by the players. Thanks for the dose of reality.
