That is plausible. OTOH, the AMD64 binaries will often require twice as much main memory, as all pointers double their size, and the Python implementation (or most OO languages, for that matter) is full of pointers. So it will be more efficient only until it starts swapping. (there is also a negative effect of larger pointers on the processor cache; the impact of this effect is hard to estimate).
