I presume so, if you start with heavy enough hammers. We have a couple of 
Davids on list, Stanwood and Love, who could do the details better than I.

The definition of "function correctly" is part of the problem. Again, the 
Moonlight Sonata players probably won't have a problem, but the Art Tatum 
fans are going to have touch weight and repetition troubles even with UW 
and DW in perfectly acceptable ranges.
