This would appear to be a logical way forward - the problem occurs when
migratory beekeepers, or neighbours, move in with other ideas. Here in the
UK we do not have the problem of very large migratory outfits, but our
beekeepers are probably in closer proximity than in the US and often favour
a variety of different races of bee; this, combined with a considerable
amount of 'local' migration makes it very difficult to maintain pure strains
in some areas.

Although F1 hybrids often display very attractive hybrid vigour, F2 and
subsequent generations tend to be far less vigorous and may, as you say,
express many bad traits of their predecessors. Whilst this may not be a
problem for agricultural crops where seed is routinely bought in each year ,
it is a problem for beekeepers because not only do they have to keep buying
new F1 queens, but they are at the same time contaminating the gene pool in
their area - making them even more dependant on the hybridising queen
producer, as they are unable to produce good queens for themselves.

Not that easy! The bees that have been here forever tend to be in small
pockets and constantly run the gauntlet of the imported bees - Italians,
Caucasians, Carniolans etc - not to mention Buckfast!!!
You do have at least one great advantage in many areas - vast amounts of
countryside with beekeepers well separated.
