The question is, what you're actually trying to achieve. You can of course use your very own MS account on your wife's new device. This way she could install every single app you've ever purchased on your account. But this also means, that she'd get all your email and so on. Not sure if you'd really want that.
My wife and our two oldest kids use WP too, each of 'em has his/her very own account. The kids' accounts are setup as child accounts of mine though so that I have a little control over what they can install and what not.
