Shimano FC-MC12 crank replacement

I'm the not so proud owner of an old (age unknown) Specialized
Rockhopper FS that arrived with a known defective Shimano FC-MC12
crank.

After some Googling, I find that Shimano will replace it with:
A new bottom bracket
IG50 chain
FC-M191 crankset
C050 SIS front derailleur
Assuming they still honor a 13 year old recall, I should probably have
called Shimano to arrange for the replacement. Instead, I dug out a
few cranks I had laying around and tried to make them fit. All of
them have the chainline too close to the frame. I also tried a few
assorted new cranks with similar results. Now, I see why Shimano also
ships a replacement bottom bracket. Duz anyone have the specs of the
FC-MC12 and the bottom bracket? Is there a suitable substitute crank
that does not require a bottom bracket replacement? Or should I just
give up trying to find a substitute and call Shimano?

Depending how picky you are, you could try shimming. I've solved similar
problems by shimming 2 sides of a square taper with Coke can material. I
worked for many months anyway (it never failed, bike was swiped).
