 As stated earlier, has anyone seen this?
 
 Along with changing the location of the piano, will a climate control
 handle this magnitude of change "outside the cavity?" 
 
 Any other ideas?

Yes. I have seen the exact same disturbances in a circa 1992 Baldwin 42"
console.  I treated it the same as you mentioned you did, and had the same
reversal the following winter.  In the past year these symptoms have not
occurred-but there is no reason to believe it could not happen again.  The
piano does not have dampchaser system and is in a large home that is heated
with Hot water radiatiors and no supplemental humidity in the winter.  I have
not recommended DC system because I frankly doubt if it would help.  Instead,
I am hoping the client will consider trading in this little troublemaker for a
more reliably-built piano. This recommendation is based on many other problems
which have also surfaced (hammer return springs are already corroding and
breaking at the coil,for one).  And on and on.
