How many bits from the key are required for the "specialisation"? If this 
number is not too high, it is possible that the data could be padded in order 
to generate different keys. Then when all the keys fit a certain 
specialisation (hash to values that start with the same bits), the data can 
be inserted and automatically have a reasonably narrow specialisation.

I suspect, however, that this wouldn't work because the specialisation would 
require rather a lot of matching bits, as this would otherwise open the door 
for rather nasty flood-type DoS attack on specific nodes or specific parts of 
the key space. Plus, if it were possible, it is especially this type of 
deliberately specialised node and it's neighbours that would be worst 
affected.
