Ammonia Pump Forensics?

Since we cannot return the broken ammonia pump for failure analysis on the ground are there any plans to conduct forensics on orbit?
Would the bulk of this work require EVAs to accomplish? What, if any, forensics have been done so far?

If there is an additional Shuttle flight added to the current manifest
(which must be in some doubt), then one of the priorities would surely be to
take the opportunity to return whatever can be retrieved from the Station.

On the other hand, I wonder if there is any way to rig the Shuttle to return
the ammonia pump on the payload bay carrier that will house AMS-2 for
delivery to ISS? How compatible/incompatible is this carrier for the ammonia
pump?

For example has anyone tried fault insertion testing on a ground mock-up to
see if what failures can be induced that mimic as closely as possible what was
observed on the ISS? Do we know at the time of failure things like pump motor
current draw? Component temperatures? Was there any flow of coolant at all?
Are we talking frozen pump? Bad electrical connections? Leaky lines?

Is Google my friend or maybe this is being kept current on a blog somewhere
that I'm missing? Links always appreciated.
