It would definitively end Jackman's take on the character, and pretty much the character itself, unless of course there is another way he gets adamantium. For that reason, I don't see it being a mind swap with 70's Wolverine. Although given the grounded setting Singer has provided, physical time travel would push the envelope a little too far on the sci-fi side of things. If there is a mind swap, I see it being temporary. More than likely it is physical time travel.
I think it would be more interesting if Logan still willingly joined Stryker and underwent the adamantium bonding process hoping that it would lead him on the path to meet Jean, possibly saving her.
