Now that actually is an interesting theory.

I was mostly just 'aving a giggle, but for the sake of the argument, it might be that the original PC-98 Alice also was a doll and simply wanted a larger body. She thus fashioned it in the form of Windows Alice, and then transfered her conscious to the larger "vehicle". Given that Windows Alice's own dolls are effectively extensions of her own will, the ability to transfer her entire consciousness to a new body is not so far of the charts.
A-and PC-98 isn't canon (or the two Alices might simply not be the same person).
Or to make it completely ridiculous, a chibified version of PC-98 Alice is sitting inside the hollow Windows Alice and controls her like a mecha suit or a piece of power armor.
