In order to get the 20x speed gain you seek I assume that Parrot would have to perform some sort of variable type inference to distinguish, for example, when a scalar is really just an integer and use an integer register. Otherwise, the PMCs in Parrot would perform much the same as the Python scalars (or whatever Python calls them).
The question is when would Parrot would perform this type inference and subsequent bytecode transformation?
