Dieter said:
As far as I see, the density of bees on small cells is higher than on normal
combs.

Bee population in a hive is regulated by many factors. small cell does not
mean a larger hive population even if there are  more cells for the queen to
lay.
Most hives stay at a certain level of population. Commercial beekeepers do
things to increase hive population.

Dieter asks:
Has anyone in the states where the SHB is a problem gained experience on
this topic?

SHB preys on weak hives. A queen breeder recently lost around 600 nucs to
the SHB.

Dieter asks:
Could the small cells with smaller bees be a good weapon agains the beatle?

 A strong hive is the key. Not a smaller size bee.
