Although it certainly won't have the appearance of the OEM unit, one way to reattach and seal the halves of the vacuum chamber is the way that the Bijur factory repaired the vacuum diaphragms on their chassis lubricator pumps. They used a pair of matching steel rings, one on each side of the prior crimp; the rings were drilled and tapped for about 8 or 10 machine screws around the perimeter to effect the clamping force.
