Great football; congrats on adding it to your collection.
I would be very surprised if inflating it slowly works given the ball and bladders age. It likely won't hold air, or will leak. Can't hurt to try as long as the leather isn't too dry/brittle.
I can recommend a restorer who I have used may times in the past, who will replace the bladder, and re-lace using antique laces (or the original laces when possible) Shoot me an email, and I'll get you his contact info if interested.
