Well I ended up finding a 15% fragment wedged behind the "cone" in the wp housing. Was a PITA to get out since housing was in place (i.e. I had not removed any hoses, just the pump). Could see piece with mirror or feel with finger tips, but not both at same time due to lack of access.
Used a bent paper clip to poke and was then able to retrieve.

So my recovery of bits of shattered impeller ended up being 95%.

Most useful tools in re & re of wp from this high-tech engine turned out to be the above paperclip and a coat hanger (to drop pump down and across rear of rad to pass side then down past frame and out).
