magic mouse to ipad via bluetooth

No

Perhaps you could but what use would it be? The iPad does not have a cursor, only an insertion point.

I suggest that you request this feature, as I have, at Apple's feature request site. Maybe if enough of us request this it will come in a future iOS release.

No.

Apple iOS touch devices are touch devices only.

Why would you want a mouse to use with a tablet.

If you need a physical mouse and keyboard, should look at and purchase a MacBook Air instead.
