No.
This wouldn't benefit anyone. If you play on Ps3, you couldn't play Morrowind, as I know Bethesda wouldn't rebuild the game to be compatible with Sony's console. If you play on PC or 360, you'll either already have a copy, or have access to one for cheap at this point.
And how would Morrowind increase Skyrim's gameplay length? Owning Morrowind doesn't magically add more content into Skyrim. They're separate games.
I only have a notebook every since my PC crashed, and it can't play Morrowind well. I can't find a copy of the Xbox Morrowind anywhere in my country right now, and importing might be a problem if there are any code restrictions.
I'm not saying Morrowind would increase Skyrim's gameplay length directly, I'm trying to say that, for example if Skyrim is 100 hours, if you play Morrowind as well you would be spending like 200 hours.
EDIT : Since the PS3 can't support it, then this probably won't happen, so I guess I have an answer. :mellow:
