I don't think it really can. What it can do is reduce the overhead (which usually translates to latency and burstiness) and the sharing.

That's taking this idea to an extreme, yes. I'd think of using something as big as an amd64 for this as "too expensive", but perhaps it's cheap enough in the long run, compared to some "optimized" design.
It would certainly have the advantage of already solving various consistency and compatibility issues. (That is, if your host CPUs is/are also amd64.)
