I would think you could treat this like you are reballing a plastic BGA.
There are fixtures (and services) that exist to accomplish this, and
many have been discussed on TechNet in the past, so you could search the
archives for "BGA Reballing".  The folks that I have dealt with for this
are Rich Sentner at Singularity Electronic Systems (603) 430-6000 and
Rich Breault at Netco Automation (978) 372-7715.
It's very straightforward, and I wouldn't think you will have any
problems making the "components".
