I think it would just be a question of the maps being able to deal with the fact that the rpms wouldn't correlate to the amount of air (3.2 vs 3.4 displacement) but I think that there must be enough room in the maps for this, otherwise lne wouldn't be able to say that a 3.6 bore works fine with the oem 3.2 tune (same thing only in reverse).

so, we need someone with a 3.2 to put a cayman airbox and maf housing in their car and push a 3.4 996 tune onto it and see if it runs ...

I think it would run ok just possibly a little too much cam too early due to the 996 timing. I would have to compare the cam timing differences.
