Only if one isn't able to manage the drone pool. The authors of the study
that you cited state:
The results show that it is possible to carry out intracolony selection
during a breeding programme for hygienic behaviour...
As this study shows, by increasing the genetic relatedness between mother
and daughter colonies from 0.15 to 0.375, one generation of multi-level
selection was sufficient to produce colonies that were twice as hygienic as
colonies from random patrilines.
