The price tag is too much, not just for the consumer, but for Sony and retailers. You'd end up with individual SKUs for Vita, PS4, and then a box with a PS4 AND a Vita which you can't break apart. That's an expensive inventory.
A better option? Drop in a $50 off coupon for a Vita in with a PS4 purchase. Add in a free PS+ voucher while reminding them of the free Vita games it offers. That will get to working in people's heads, like they're wasting money if they DON'T buy a Vita.
