Greetings, 
   Hmm,  I would think you should raise the entire action to the same height 
as the other one, since these actions' heights were originally indexed to the 
plate height.
This isn't hard to do with well-glued shim stock under the key frame.  The 
glide bolts should be able to extend far enough down to accomodate.  
  What  sort of hammers are these two actions going to have?
