  Yes, there is a point of inertia becoming a problem.  
What are the front weights of the keys?  If you get the middle section much 
above 30-35 grams of front weight, you will run into inertia problems.  The 
bass keys on many full size grands will allow about 45 gr. front weight max. 
before turning into "trucks".  
   If the action geometry fits all the specs for dip/blow considerations, 
then the hammer weight should be examined.
