I agree with Jonathan Holmes.  I see no purpose in converting one
system to another system.  The only way I would consider it would be
if it could be put back without damage in a short period of time.
If it is something that there are lots of them around, that might make
it more acceptable.  For example, I have no problem with converting to
a nickelodeon many of my 200 player pianos I have stored.  Some of them
are rare, however, and they would never be changed by me.

I have seen one Duo-Art grand that had a separate box attached.  One
could play Duo-Art rolls as from the factory, but you could go to the
cabinet next to the piano and put on an Ampico roll which would use the
Duo-Art stack with the Ampico works found in the cabinet.  That would
be acceptable to me.
