No. Just no way in any hell in any universe. I love Mass Effect, but this proposal is 10999% doomed to Marty Stu-driven WH40K canon defilement. The anymosity between the chapters existed even BEFORE the Horus Heresy, so it goes 10,000+ years deep between extremely long-lived individuals, with each group being different to all others on the genetic level.

And that is before I mention that any Shepard that is less than a full-blown, 100% Renegade is going to be executed for heresy in WH40K by the first Inquisitor they meet.
