I have been a little bit of a metal worker(though not on that scale), and I'd hazard to guess that it's a lot more involved than that. The expansion rate of aluminum, it's relative strength per thickness, the list goes on. I'd imagine it's significantly different.
But I bet plasma coated steel parts, cryo treating, and damn careful assembly could get you close...
It'd cost a bomb, but I swear you could get a heck of a lot more power from the 617, and I bet with a good degree of reliablility too. So what if you cut it's life span in half, then it will only last 250K miles?
