For future reference, questions like this more fit in Gear Building and Customizing.

IIRC, swapping necks depends primarily on the scale length of the guitar. If the scale length is different, then no. Considering how they have different numbers of frets, I would say it would not work but that is just a guess without knowing their actual scale lengths. Also you have to worry about neck action, screw placement, shimming, and the like. Since your messing around with Squire guitars, I do not think it would not be worth bothering. Likewise if you mess something up you are not ruining expensive bits of kit, either.
